It's a nice design! But I'm sure I've seen that image somewhere before. I used it in one of my backgrounds! It's the first thing that comes up when you put underwater into google images! http://www.eyesontutorials.com/image...r_1024x768.jpg
By the way, please take some care into researching where it came from before calling it a rip. But I understand, rippers are the scum of the freelance world, heh.
It's not used as anything else, except a "filler image". To help make it look nicer. You can't "rip" a background image that's freely given on the web. Anyway, good luck with the sale Ezia.
