Pat.
Please don't spend a lot of time on photos. I know what works when they have to be resized to 160x80 and tanks with foliage all over them just doesn't work. What I have in the game now is in most cases "good enough" for the various models. If there's one that's not you can point it out and I will go find a game suitable photo.
Just remember, just because it might look great in full colour at 600x 900 res DOES NOT mean it will reduce to a workable photo using a limited grey scale reduced to 160x80 for use as a PIC in the game
That said the photo you used for your experiment loads OK but it just isn't what I want in the game
