Frankly I'm a bit horrified. This stuff is good. I mean it's really good and I don't know what that means. Certainly for concept art for games and movies this ability to endlessly remix and generate new images from existing content is a game changer.
The results were wildly better than I expected. So good in fact that I was up half the night thinking about what this means. I think I have future shock. :-0
Here's a link to a tutorial that will get you started but essentially all you need do, is scroll down until you see the description of the image and replace that with your own text, then wait fifteen minutes.
