While I understand that the developer of GD removed GIF support for (what to him is) a good reason, there are many of us who still rely on GIFs for much of our work, especially given the lackluster adoption of the PNG standard by most browser developers. I'd be really interested in finding a way to roll GIF support back in to the new GD code in PHP under OSX (I've already found a way to do it under my main FreeBSD servers).
Additionally, I have wanted to build and install the Ming Flash creation library into PHP. I'm aware of the FreeMovie alternative and, while it shows promise, it's not as rich as Ming yet. If anyone has successfully done this, I'd love a HOW-TO.
