in reply to Preventing an image from caching

If you are generating the page, append a random number to the call for the image. 
<IMG SRC="/cgi-bin/image.pl?rand=4531269823">

[download]
Each time the page draws the string will be different, eliminating the cached image problem because to the browser it is not the same image.

    Thanks for the post, but I am generating the image, saving it to a file, then calling the file with the <IMG...> tag. I can't seem to get the image to go directly to the page because all I get is ASCII text instead of hte binary.

      Call the file with this script. 
      #!/bin/perl

$image = `cat imagenameandpath`;

print "Content-type: image/png\n\n";
print $image;

      It's the simplest way i know.

      BTW- image/png is for png file format, substitute gif, jpeg, for others.
