Limited Time Promotion Thumbnail Screwed Up

i have a promotion running for an image that is mostly bright red but (see image above) something went badly wrong. i set up the promotion my time last night (central european time) and tried to fix the problem twice by deleting and recreating the promotion... no go. it is currently on page 8 of the promos:

this is what it is supposed to look like:
