code:

foreach $file (@files) {
	$size = -s "$file" ;                #Problem line - supposed to get the filesize.
	$file =~ /(.*?)\s\d/;               #Get just the name, not the number, of the file
	$filecrop = $1 . " " . $size;       #Put it all together.
	print $filecrop . ".jpg" . "\n";    #This is filler for the file manipulation.
