It comes from ImageMixin which is mixed into ATBlob in content.py for 
backwards compatibility with ATImage. The blob-based File and Image 
types are both actually instances of ATBlob.

If you're looking for a generic way to see if an Archetypes item has an 
image, it's probably best to check if there's a field called 'image' in 
item.Schema()
