uncache_image weirdness

[Miles Bader]

In the new function you wrote, "uncache_image", I don't understand why you
call lookup_image (the return value isn't even used).  Wouldn't it work to
just search the table and free any matching spec, _without_ calling
lookup_image?  In the case of an image that isn't actually in the cache, it
seems silly to load the image just to immediately free it...

Thanks,
