That's exactly right - some of them are clearly based on photographs but the characters in the foreground have been coloured over, as you say.
I've been improving the site's media section. It now takes a stab at displaying human-readable file-sizes alongside media files. I can improve that further. It also works out what kind of file it should be from the file extension and displays that separately to the filename:

These changes need to be applied to the downloads sections too.
What's more relevant to this discussion is that I put the filenames below each image. It took time to do because some of the images have very long numbers as their filenames and I needed away to break those numbers up so that they wouldn't break the layout of table.
I made the media part of the site originally to show off the images of the game originally and I didn't really want filenames shown below the thumbnails.
When you get into the Star Fleet section through, there's all sorts of things mixed up in there which need to have a description below them. Otherwise it's hard to make sense of all that you're looking at.
So, I'm grateful for the feedback on that.
Hopefully, that should make things easier to find.
You can also turn off the filenames on the images:
