If you’re spending a decent amount of time manipulating images in php using GD or command-line ImageMagick, you should check out the Imagick php extension. Imagick provides an object-oriented interface to the ImageMagick API.

As far as I can tell, this extension was left for dead a while ago but revitalized over the last year or so and is now rockin pretty hard. The developer is pretty responsive on the Imagick board at the ImageMagick forums as well, and he’s got lots of nice code tidbits on his own blog.

There is also the MagickWand For PHP extension, but I found the syntax pretty odd to deal with, it probably relates more to the way GD works than the OO style of Imagick.
