Another way you could get some "payment" would be to make a good enough instructable that you can get it featured, which will get you a short pro membership, which you could sell to someone. But it would not sell for very much. The good thing is that you will not get exploited by instructables. Face book takes ownership of all pictures that are posted there and has been known to sell them to whoever is interested. On instructables you maintain ownership of everything that is posted. If they want to put perhaps put one of your instructables in a book, they will ask for your permission to do so.
