I've just looked at the free puzzles, and there are a couple I haven't done yet. Oh goody!!!!!
Alison, check out the history via a search engine, and the title is also a clue. Sometimes it helps to lighten or darken the screen, other images appear. Also, if you use your mouse to go over a picture, sometimes there is a reaction.
