We heard from the great and powerful Jot. The problem with the greyed out images have to do with the datacenter. There apparently is a bug in the graphics application at that level and they informed Jot that it may take a GOOD while before its fixed.

He is not going to let us down despite this setback and is working on a work around to the problem.

But in the meantime, it would be best to forgo the jpg images and stick to gifs and pngs.
