ImageWalker will show all image files in the current folder.
For more information on file formats click here.
ImageWalker currently supports the following image formats:
Image Walker also supports various media files. Displaying of these media files requires Windows Media Player to be installed.

JPEG (Joint Photographic Experts Group)
JPEG image compression method works well on photographs, naturalistic artwork, and similar material; not so well on lettering, simple cartoons, or black-and-white line drawings (files come out very large).
JPEG is "lossy", meaning that the image you get out of decompression isn't quite identical to what you originally put in. The algorithm achieves much of its compression by exploiting known limitations of the human eye, notably the fact that small color details aren't perceived as well as small details of light-and-dark. Thus, JPEG is intended for compressing images that will be looked at by humans.
A lot of people are scared off by the term "lossy compression". But when it comes to representing real-world scenes, no digital image format can retain all the information that impinges on your eyeball. By comparison with the real-world scene, JPEG loses far less information than GIF.
Quality v Compression
A useful property of JPEG is that adjusting compression parameters can vary the degree of lossiness. This means that the image creator can trade off file size against output image quality.
For good-quality, full-color source images, the default quality setting (Q 75) is very often the best choice. Try Q 75 first; if you see defects, then go up.
GIF (Graphics Interchange Format)
It is an 8-bit format, which means the maximum number of colors supported by the format is 256.
There are two GIF standards, 87a and 89a (developed in 1987 and 1989 respectively). The 89a standard has additional features such as improved interlacing, the ability to define one color to be transparent and the ability to store multiple images in one file to create a basic form of animation.
ImageWalker can combine multiple images to a single animated gif?
PNG (Portable Network Graphics format)
In January 1995 Unisys, the company CompuServe contracted to create the GIF format, announced that they would be enforcing the patent on the LZW compression technique the GIF format uses. This means that commercial developers that include the GIF encoding or decoding algorithms have to pay a license fee to CompuServe.
However, a number of people banded together and created a completely patent-free graphics format called PNG (pronounced "ping"), the Portable Network Graphics format. PNG is superior to GIF in that it has better compression and supports millions of colors. PNG files end in a .png suffix.
JPEG is not going to displace GIF or PNG entirely. For some types of images, GIF or PNG is superior in image quality, file size, or both. One of the first things to learn about JPEG is which kind of images to apply it to.
Generally speaking, JPEG is superior to GIF or PNG for storing full-color or gray-scale images of "realistic" scenes; that means scanned photographs and similar material. Any continuous variation in color, such as occurs in highlighted or shaded areas, will be represented more faithfully and in less space by JPEG than by GIF or PNG.
GIF OR PNG does significantly better on images with only a few distinct colors, such as line drawings and simple cartoons. Not only is GIF OR PNG loss less for such images, but also it often compresses them more than JPEG can. For example, GIF OR PNG compresses large areas of pixels that are all exactly the same color very efficiently indeed. JPEG can't squeeze such data as much as GIF OR PNG does without introducing visible defects. (One implication of this is that large single-color borders are quite cheap in GIF or PNG files, while they are best avoided in JPEG files.)
JPEG has problems with very sharp edges: a row of pure-black pixels adjacent to a row of pure-white pixels, for example. Sharp edges tend to come out blurred unless you use a very high quality setting. Edges this sharp are rare in scanned photographs, but are fairly common in GIF OR PNG files: borders, overlaid text, etc. The blurriness is particularly objectionable with text that's only a few pixels high. If you have a GIF or PNG with a lot of small-size overlaid text, don't JPEG it.
Plain black-and-white (two level) images should never be converted to JPEG; they violate all of the conditions given above. You need at least about 16 gray levels before JPEG is useful for gray-scale images. It should also be noted that GIF or PNG is loss less for gray-scale images of up to 256 levels, while JPEG is not.
The address bar shows the current folder that ImageWalker is viewing. Selecting a new folder with the address bar will change the current folder.
You can type a new folder name directly into the address bar. To enter a new address:
You can enter either a fully qualified path ‘c:\Images\My Holiday’ or relative path ‘My Holiday’. Entering ‘..’ will take you to the parent folder.
The escape key will cancel editing of the address bar.
To search sub folders for image files using ImageWalker:

TWAIN defines a standard software protocol and application programming interface (API) for communication between software applications and image acquisition devices.
ImageWalker can use TWAIN to capture Images from digital cameras or scanners.
To select a TWAIN-compliant device, scanner or camera, for acquiring images:

ImageWalker can use cache files to speed up its operation.
Turning off special effects in the view options can also improve performance on slow machines.
Cache files are databases of pre-generated thumbnails.
Normally every time you browse to a folder, ImageWalker needs to generate thumbnails for any images found. Generating these thumbnails can be slow.
If a cache file exists, thumbnails can be loaded and displayed quickly.
Note:
Depending on what your doing several ways to control the thumbnail size exist.
A wildcard character is a keyboard character such as an asterisk (*) or a question mark (?) that you can use to represent one or more real characters when you are searching for files or folders. Wildcard characters are often used in place of one or more characters when you don't know what the real character is or you don't want to type the entire name.
You can use the asterisk as a substitute for zero or more characters. If you're looking for a file that you know starts with "summ" but you can't remember the rest of the file name, type the following:
"summ*" (without the quotation marks)
The search will locate all files of any file type that begin with summ including "Summary.txt", "Summary.doc", and "Summer.doc". To narrow the search to a specific type of file, type:
"summ*.doc"
In this case, the search will find all files that begin with summ but have the file extension ".doc", such as "Summary.doc" and "Summer.doc".
You can use the question mark as a substitute for a single character in a name. For example, if you typed "summ?.doc", the search would locate the file "Summ1.doc" or "Summ2.doc" but not "Summary.doc".
You navigate through your system with ImageWalker the same way you would with Windows Explorer.

ImageWalker supports interaction vie OLE automation. This means you can control it through scripting or Visual Basic.
Currently supports only a single method to open a specific folder. The following example will open ImageWalker in 'c:\'
Click here to test ole automation!
The scripting to accomplish this operation is as follows.
var obj;
obj = new ActiveXObject( "ImageWalkerViewer.ImageWalker" );
obj.OpenFolder("c:\\");
or in VB:
dim obj
set obj = CreateObject("ImageWalkerViewer.ImageWalker" )
obj.OpenFolder "c:\"
The following code will open ImageWalker in the same folder as the web page!!
dim s
s = mid(window.location, 9)
While Right(s, 1) <> "/"
s = Left(s, Len(s) -1)
Wend
s = Left(s, Len(s) -1)
s = Replace(s, "%20", " ")
s = Replace(s, "/", "\")
set objIW = CreateObject("ImageWalkerViewer.ImageWalker")
objIW.OpenFolder s
The ImageWalker web page contains a tutorial showing how to create Web Pages step by step.
Tips:
Hypertext Markup Language (HTML) is the language of the World Wide Web.
HTML is the language that web pages are written in. It is displayed as a web page by a Web browser such as Microsoft Internet Explorer or Netscape Navigator.
HTML is an open standard, owned and updated by the World Wide Web Consortium (W3C). It is fairly easy to learn, and many online references and how-to books can help you learn it. A quick trip the HTML area on the W3C site or to your local library or bookstore should get you started.
If you want to see some HTML, click View/Source from the menu in your Web browser (or right-click in Microsoft Internet Explorer and choose View Source) to see the HTML code behind the page you are reading.
Cascading Style Sheets (CSS) are design templates that provide augmented control over presentation and layout of HTML elements. They allow you to separate the way you design information from the HTML content.
CSS enables you to control the margins, coloring, background images, fonts, and a whole range of elements for virtually every individual element that an HTML file describes (<BODY>, <HEAD> (header), <P> (paragraph), <UL> or <OL> (lists), <TABLE>, and so on).
Using style sheets, you can create Web pages with minimal graphics, and therefore much smaller downloads. Style sheets also provide you with a higher level of typographic control, and they enable you to make changes to an entire site through the use of linked style sheets.
File Transfer Protocol (FTP) is a method for copying files between computers connected to the Internet.
To transfer files using FTP, download an FTP client such as WS-FTP (for Windows) or Fetch (for the Macintosh). Instructions for obtaining and installing these programs are available on the www.download.com.
In most cases your domain host or web page host will be able to provide you with information on how to use FTP on their site.
An online tutorial on using FTP exists on the ImageWalker web page.
When ImageWalker creates a web page it combines a web page template (HTML), a style sheet (CSS) and a series of images.
Both the style sheet and the web page templates can be edited and modified by the user.
In a default installation templates used are located in the folder:
C:\Program Files\Walker\ImageWalker200\Web Templates
You need to add an INI file into the template folder for each template you create. ImageWalker will automatically detect new INI files.
The INI file is an ASCII text file that contains sections and keys. Section names are enclosed within brackets. Each key contains one or more entries, each of which has the following format:
name = value
The ImageWalker INI file contains the following sections:
[Index]
template=standard.index.html (This is the template for the index page)
[Image]
template=standard.image.html (This is the template for each image page)
[Required Files] (Include any additional required files)
1=__up.gif
2=__back.gif
3=__next.gif
The Index and Image templates are standard HTML but contain the following tags that are replaced by the wizard:
In the index template:
In the image templates:
The most common way to edit image descriptions is from the description view in ImageWalker. To do this:
Tips:
Note:
ImageWalker stores descriptions in IPTC format inside the image file. For more information see Where does ImageWalker store the Image Descriptions?
ImageWalker stores description information inside the image file itself.
Many good reasons for storing image descriptions directly in the image file exist. You can rename copy or email the image and the description information remains intact.
The description information is stored inside your image files in a standard IPTC format. The ITPC format is widely supported by many programs including Adobe Photoshop.
ImageWalker can read and update the IPTC details from Jpeg, TIFF, Gif and PNG files currently.
IPTC stands for the International Press Telecommunications Council.
ImageWalker supports the information standard developed by the Newspaper Association of America (NAA) and the International Press Telecommunications Council (IPTC) to identify transmitted text and images. This standard includes entries for captions, keywords, categories, credits, and origins.
The caption and keyword entries can also be updated and viewed by many other third-party image browsers and editors including Adobe Photoshop.
More information can be found at www.iptc.org.
ImageWalker 2.0 can import descriptions written by ImageWalker 1.05 in the description.xml by using the Description Import Wizard.
If anyone has additional image description formats that they would like to import or export please contact Support@ImageWalker.com.
