Assuming this is a complete list of the possibilities 

my $content = ....;
my %counts;

$counts{ $_ }++ 
    for $content =~ m[logo_([^_]+)_20x10\.gif]g;
print "$_ : $counts{ $_ }\n" for keys %counts;

Examine what is said, not who speaks.
"Efficiency is intelligent laziness." -David Dunham
"When I'm working on a problem, I never think about beauty. I think only how to solve the problem. But when I have finished, if the solution is not beautiful, I know it is wrong." -Richard Buckminster Fuller
If I understand your problem, I can solve it! Of course, the same can be said for you.
