Objective: Get images to print 20 per page in a specific order.

Success: The first page prints in order I specify nicely (it prints the 20 newest images stored into the database).

Failure: When you reach over 20 images and you use the url_param, the images on this new page aren't in the right order.

Example: If I have 23 images, I'd type in script.pl?page=2 and it SHOULD print the first three images (but it doesn't).

Can someone check the math to see if I'm going about it correctly? 

my $page = url_param('page');
my $top = -($page * 20);
my $bottom = $top + 19;

if ($page ne "") {
for ( grep defined($_), ( reverse keys %upload )[ $top .. $bottom ] ) 
+{
