Make tests a little more resilient

PNG allows identical images to be stored differently what makes nearly all
tests checking the MD5 hash of the PNG representation fail with external
libgd. For now, we use the GD format instead, which doesn't allow for such
differences.

Of course, this md5() checking should be replaced by a image diffing feature
in the long run.
