hiya mate,
your best bet is to check out
www.hotscripts.com! they have a php/tutorial section...
http://www.hotscripts.com/PHP/Tips_a...ion/index.html
there you go, something to chew on for awhile. goodluck. and if you run this locally, and it's on a windows machine, make sure to go into php.ini and take off the ';' for the php_gd2.dll lib
goodluck!
Cheers,
Jacob
