Having inline images in your Web pages is sometimes problematic for Web
surfers coming in over slow phone lines. Some ways to reduce their pain:
Use GIF format for diagrams and JPEG for photographs. GIF format is
"lossy;" some of the details of an image or removed and lost
to save space. For diagrams, this is usually not a problem; for
photographs, clarity and sharpness are generally the goal.
You can use imgview to change image format types.
For large files (especially JPEG files), use small thumbnails inline
and link to the larger version of the image. This will help increase
download time for the page quite a bit, as well as give the user the
option of not viewing an image in which they are not interested.
If you have text images, consider converting them to ordinary text if
possible.
Use imgview to reduce the number of colors in a GIF image to
conserve disk space. You can also retain the TrueColor setting and
manage the image quality of JPEG files in imgview, saving
additional space.
You can allow Cosmo Create to insert image Height and Width
automatically. Choose Element > Inline Attributes, and
set Width and Height to Pixels.
