Thanks! I knew I made some mistakes. :)

I finished the PHP4 class, but the problem is that PHP4 does not have file_get_contents. I don't really understand sockets, so caching isn't going to workout. Maybe someone could contribute some PHP4 code that mimics file_get_contents.

Here are the two files again, PHPGravatar(4).class.php is the PHP4 file.
