I'm in the final stages of creating content for the soon-to-be-more-than-just-a-holding-page phpgd.com. This site is basically a one stop shop for all things PHP GD related .. script, articles, etc. It's not the most technologically advanced site ever, but that's not the aim.
If you've written any scripts that utilise GD to do something to images whether it's modifing existing ones or creating new ones, please feel free to drop me a PM here or an email ( chris at ooer.com ) and if it's something that's not been covered, or if your code is better than whats there now, it could be included. All code is attributed to the author with a link back to your site/email.
Likewise if you have any interest in writing an article about something GD related .. get in touch.
Sadly I can't pay anyone for anything. Hence the "volunteers" posting..
PS. No thumbnail scripts.
