I was thinking about something. This might be very time-consuming and not as personalized as what you are looking for, but I know how wonderful it feels to have a visual support for your work.
Have you tried to find "Creative Commons" images, on deviantart, for example? Now "Creative Commons" are under license. You are allowed to use them under certain conditions and these depend on the artist. But there are some works under creative commons that are so flabbergasting that you will get blown away and inspired like no one's business.
