Have you tried describing the image in the alt tag?
Personally, I wouldn't worry about text on the page. I'd describe the picture to some one it doesn't load for ... I don't in any way mean keyword stuff ... I mean they say a picture is worth 1000 words, I'd use some of them ... 200, 300, 500 whatever it takes to describe the actual image ... IOW: I'd tell the story of the images on page in words and see what happens.
