Anyone with more than a handful of pictures with know that even with the most verbose filenames it can still be hard to track down the particular image which you seek. So people have written various proggys to catalogue your pics. The simplest of these being those that create thumbnails (small versions) of your pics and generate a HTML file to allow them to be viewed in favouite browser. You've guessed it this is what CreateIndex does!

• Requirements
  • An Amiga!
  • ImageStudio, available free with CU Amiga May 1997
  • Arexx, preferable running
  • Graphical HMTL viewer, a browser or HTML datatype, only neccessary if you wish to view the results!?
• Features
  • Small, its an Arexx script
  • Fast, uses ImageStudio rather than datatypes
  • Update index, doesn't regenerate thumbnails
  • Can generate image dimensions for progressive loading, alternative version
  • Generates text links for unrecognised files, this is mainly because ImageStudio can't load progressive jpegs (its only failing), but you could actually create a table of document links!
  • Generates multiple pages with previous and next links
  • Writes the sizes for all the thumbnails for fast loading of tables
  • Loads of comments in the script, simply unheard of!
  • Some extra scripts that may be of interest

Copy the files from the Rexx directory to your ImageStufdio/Rexx directory. Stick this file where you like it. That's all.

• CreateIndex.isrx - original script

Extra Scripts

• Convert2PNG.isrx - does exactly what it says
• Convert2PNG16BW.isrx - generates 16 colour greyscale PNG, useful for black and white artwork
• BatchProcess.isrx - update of original example script, now supports all formats that ImageStudio has
• BatchProcessNotify.isrx - update of original example script, now supports all formats that ImageStudio has

Initially : Open the scripts window in ImageStudio and double click on CreateIndex. Shift select all files you want to be in index or just hit 'All'. Wait with baited breath. A file called index.html will be generated in the directory as well as the thumbnails. If you have selected more than row*columns images (default 10*5=50) additional files called index2.html etc. will be created.

Updating : If you have added more files to a directory simply repeat the previous process the file pattern will be set not to show the index files (other html files will appear) or any thumbnails.

Advanced : All the parameters are constants defined in the script itself this means if you want to change things you will need to edit the script yourself Shreaks of horror!!!. Don't worry its dead easily if you can type and breath (preferably at the same time). All the values that you may wish to change are near the top of the script:

/* PROGRAM CONSTANTS - change these values to suit */

HTMLFile='Index.html'   /* What to call the html file, Oh Yes */
SquareSize=100	       	/* Size of square into which to fit pic */
TNFormat='PNG'          /* Thumbnail file format */
TNArgs='INTERLACE=ADAM7'/* Thumbnail file format arguments */
TNExten='png'           /* Thumnail file extension */
TNPrefix='TN'           /* Thumbnail prefix */
TableColumns=5	      	/* No. of pics per row */
TableRows=10            /* No. of rows in table in each index file */
TableBorder=1           /* Size of table borders, in pixels */

FilePattern='~('HTMLFile'|'TNPrefix'#?)' /* only change if you understand arexx */

Minimise the image window before batch processing a lot of images as it will make the redraw time shorter and decrease the time for the batch process to run

All done! (Hopefully)
