[url=http://www.perldoc.com/perl5.6.1/pod/func/substr.html]substr is your friend. It will allow you to extract any number of characters from a string.
It works like this:
# start at, stop at, replace with (if anything)
my $first_4 = substr $var, 0, 4, 'newtext';
In your scenario, you can use substr like this to get what you need:
[perl]my $var = "21f2.albumimage.jpg";
my $first_4 = substr $var, 0, 4;
print $first_4;[/perl]
