Looking at the category choices for uploading of photos, I do not see an option for the Armorama completed models such as German WW II AFVs. How does one get a photo in that gallery or the diorama galley?

Is it possible to transfer a photo to one of those categories from my current My Photo gallery, or does it only work to upload from my computer?

Finally, I have adjusted some of my photos on my computer to be displayed in black and white, but when uploaded they turn out back in color. What happened? Any help here is appreciated.
