Go re-read the docs (or i should say: go re-read the examples & source since cgi-lib.pl is so horribly documented)...

It doesn't return a hash, or an array.

if (($in{'pic'} =~ /^[a-z0-9-_]+\.jpg$/i) && ($in{'cat'} =~ /^[1-7]$/)
+) {
  &showPic($in{'pic'}, $in{'cat'}); }
elsif ($in{'cat'} =~ /^[1-7]$/) {
  &showCat($in{'cat'}); }
else {
  &showError;
}

Hmm... That is a hash, isn't it?

Doh... Ofcourse I can't use the return value of the function, since it's just that - a scalar. Anyway, I use the hash %in that's defined in the function itself, it caries all keys and values.

The script itself works, I've been using it this way in several websites... I just really want to start using strict and get a better understanding of it all, instead of just 'making it work'.

Ofcourse, that doesn't mean that it shouldn't work... :)
