The one source I would stongly recommend, would be Squadron Signal's M4 Sherman Walk-Around. It goes for about ten or twelve bucks and has a ton of pictures that show most anything you can find on a Sherman. I have found the detail photos in it to be incredibly valuable on my current M4 project.
As far as scanning photos from it and publishing them for viewing here, that is not an option because doing so is specifically prohibited by the publisher's copyright.
