I like the idea. It makes sense to allow pages with only images missing in the back-forward cache as makes bf cache usable in many more cases without much danger of breaking anything.

This patch should also check the pending resources in the documents CachedResourceLoader. The subresource list in the DocumentLoader is not reliable (In case multiple documents load the same resource in parallel, only one of the subresource lists has the resource. On the other hand some resource tpes are loaded using SubresourceLoaders directly and don't show up in the CachedResourceLoader. Yeah, it is a mess.) 

Shouldn't you somehow trigger loads for missing images after you restore the page from the cache?

This is significant browser behavior change so maybe it should be a setting?
