Bill,
You're doing just fine... you gotta start somewhere. What you are
doing is just the first line of defense. Some links to check out:
These are a good start-
http://www.php.net/manual/en/function.gd-info.php
http://www.php.net/manual/en/function.getimagesize.php
These may take more effort-
http://www.php.net/manual/en/function.imagetypes.php
http://www.php.net/manual/en/function.mime-content-type.php
http://www.php.net/manual/en/ref.fileinfo.php
