Your basic problem is that you're not updating $pics_found in your top while loop, like you are in the bottom loop. By the way,
$pics_found = $#found_images + 1 is an ugly way of saying
$pics_found = @found_images, since an array in scalar context returns its size. There's really no need for a separate variable, then! Also, move your $limit_img_size logic to the inside of the while loop. The two loops do the same thing, there's just a slight bit of extra logic if $limit_img_size is "yes".
while (@found < $pics_to_find * 30) {
last unless @found_galleries; # exit the loop if there are no more
my $gallery_content = get(pop @found_galleries);
while ($gallery_content =~ /.../) {
...
# why use "yes" and "no"? why not just a true value or a false va
+lue?
next if
$limit_img_size eq "yes"
and !some_size_constraint();
push @found, ...;
}
}
