This way it's incredibly fast, rather than loading them all into memory and iterating. Especially useful for sites with large image libraries.

Thanks for the suggestion jake - I'll have a look at this locally :)

Won't image be a list var here, returned from chunk_images? .update() won't work.

Slicing querysets generally produces querysets, but i'm not sure how that fairs with the mutation that chunk_images is doing.
In my testing it did return lists, although I thought that was something going weird as I had no images locally. If it doesn't work I'll just have to tweak chunk_images, but that shouldn't be too difficult.

Untested in its whole, but the theory should be sound.
