Regarding the use of lowercase, there's couple of articles somewhere, I think written by the good DrByte -Image Filename conventions and Image Preparation-how to that indirectly address the use of caps in files names, and then the forum posts by lindagal2, mc12345678 and the Dr. "How do I add _MED and _LRG product images?" all in aggregate, including examples, my mind merged everything and I figured out to use all lowercase---- Not to bad for me really! I use upper case MED and LRG though.....
