Editing Photos

[CheekyChops]

Is there any software I can download or a website where I can upload photos and 'manipulate' them?

It's hard to explain what I want, I have a friend that is emigrating next week and for her leaving party we thought we would get some photos of her and 'alter' them slightly, add captions - that sort of thing, to make some posters we could put up round the room.

Any ideas?

The Gimp will do everything you want.

But it's not the easiest thing in the world to use if you're not used to these kind of programs.
