I see this question come up alot, so I decided to see what I could come up with. Run this script in a directory, and it will produce thumbnails of all jpgs, make an html page with them all in a tables, with a javascript popup window to view the full image.

The interesting part of this script is the various methods for closing the popup window. You can use which one suits your purpose. I included 3 methods. The onBlur closes the popup when the mouse leaves it. This can be handy if all the images have different dimensions, otherwise the popup will stay open and display a mis-matched photo to popup. Play with it, and you will see. If all your images are the same size, it works great, because you can remove the onBlur and let each new thumbnail be displayed in the same window.

#!/usr/bin/perl
use warnings;
use strict;
use Image::Magick;

#watch the width of your picture names 
#they can widen the table cells if too long 
umask 0022;
my $image = Image::Magick->new;
my $count = 0;

open(OUT,">thumbs.html");
print OUT<<End_Header;

<SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript">

return false;
