I'm curious to know what the difference between the two is. I believe my server supports both. I'm wondering if there is a advantage to using ImageMagick vs. GD.
Edit: I've found a post after doing a search which gives me some of the info I wanted. Now is there a problem with switching Photopost over after installed?
I've switched between them several times with no apparent problems (after a recent server failure my host changed the path to mogrify so I switched to GD2 until I discovered the new path, then back to Imagemagick).
