So that this way for every document I have on my system I will be forced
to also store a second image file?

Honestly, if the components are very light, and if they are designed
intelligently (i.e., they "throttle" themselves down so they don't eat
99% of the CPU), you'll end up with a progressive update of the image. 
The machine won't slow down that way during image generation.  Also, if
the components "keep-alive" for a while, they can cache some images (not
too many) so a user that switches between viewing documents a,b, and c
won't have to wait for them to be re-rendered every time.

If you guys *do* decide to go with a stored thumbnail (which, I guess,
would be good for certain users) at least make this an option somewhere,
so people with lots of processor and little hard-drive space (/me waves)
don't suffer too much.  I went thru and deleted a bunch of backup files,
cache files, and a couple thumbnail directories (which I'm not all to
sure why they were there...) and free'd up 70% of my used hard-disk
space.  I don't like unneccessary caches.  ^,^
