Ahh, I think that most people who have put things in free stuff would agree that all images (including animations) can be used commercially. I think that the non-com rules apply to the distribution of the item itself or it's dirivitives. For example I put a texture in free stuff, don't package that texture with a charater you want to sell, don't copy & paste a piece of my texture put it together with another texture and then sell it. But if you put the texture on a figure, render it, and want to use the image for say, a book cover or whatever, be my guest. But if you have a question about it, ask the person who posted it, if you can't get ahold of the person and there is no mention of it in the read-me, then just use the item for your commercial renders.
