In case you're wondering exactly how that works, perl is implicitly splitting the output on a newline character, because it's being assigned to an array. The following is an equivalent, explicit version of what's going on. 
my $files = `find ./Images | egrep '\.jpe?g$'`;
my @files = split(/\n/, $files);

UPDATE: My split was slightly off, as corrected below. Who does this guy think he is, correcting my code? ;-)
