Hi! I've found some problem using GD for resizing images: if the image is too big you can have error like:
Fatal error: Allowed memory size of 12582912 bytes exhausted (tried to allocate 1600 bytes)
With ImageMagick the problem doesn't exist.
Is it possible to use ImageMagick instead of GD?
Or it's possible to write a plugin that replace the wp_create_thumbnail() with a new one (the ImageMagick one)?
