Are these subtitles images, are larger graphics for something? Taking a guess, it looks like you might trying to use colored images for some kind of feature, and it's complaining about them being too large. (Large in the sense of memory, not resolution). You might need to make them physically smaller, or use less colors if you can (assuming I'm right about what you are doing...) I'd have to see what you are trying to import to know for sure (but maybe others have encountered this...)
Also, the last error I've never seen before, but it sounds like your images are changing size too frequently in a short period of time...
You have 2 months to ask Sonic! Hurry, pester them!
