not sure what you are trying to gain out of providing these to affiliates, but overall I wouldn't say many people would be using them

I am not sure who you are trying to target with these, tgps or blogs?

there is barely any text on them, so blogs won't use them, and the pics are too big, so tgps won't use them

It seems you are just using the galleries and feeding the rss with them

I would reduce the image sizes to a standard thumb size for tgp's and just market them as "gallery rss feeds", because unless you are going to add at least a paragraph or two of text, you won't be able to tap into much blog traffic
