Well I don't really have much else to submit to this problem because it was covered by everyother person in the Monestary but I have one suggestion. Why don't you use substring instead of pattern matching to limit it to jpeg. Here is an example that should work... 
my $jpeg = 'jpg';
if (lc(substr($upload,length($upload) - 4,4)) eq $jpeg){
    ...do crap    
}

Then after that, you could do a s/// or t/// to replace .jpeg to .jpg, or just tweak with that a little. Best of luck!
