php image library VS ImageMagick

[Matth_S]

Hi,

I use the php standard library to convert image format and create an image from different thumbs.
But maybe it's a little heavy for the server to do so (the process is exectued in a loop).

I've heard of "ImageMagick" to convert image and create image ; etc.

So do you know which one is better to have the lowest server process ?

Thanks
