Hi Helena,
Yeah, I was talking about extending the ImageReader, which already
handles the resizing, to just write the newly resized image to disk. 
I want this because of the memory intensiveness you've mentioned.  It
turns it into essentially a one-time (hopefully non-cached) cost, then
subsequent requests are read straight from disk instead of resizing
yet again.  I think this is a reasonable medium between pre-generating
everything and dynamically generating everything.
