You didn't say what OS. If you're running Linux (or almost any UNIX based 
system), then I'd do something like:

if (`file $file` =~ /JPEG/) {
        print "$file appears to be a JPEG file.\n";
} else {
        print "$file does not appear to be a JPEG file.\n";
}

print "$file is ",-s $file," bytes.\n";
