It might be better, if feasible (I don't know), to do it the Aperture / Lightroom way. As far as I remember, these programs don't store modified copies of the photo, but only change sets (mask this zone, change brightness, blur something, etc). Aperture, particularly, applies the changes using the GPU for its preview to be instantaneous (but Lightroom doesn't AFAIK, so it's doable only on the CPU). 

Caching some sort of thumbnails would also be an option to make it speedier (say, after applying the effect on the CPU, a thumbnail on that zoom level and the general thumbnail for picture browsing, or whatever). 

This way, even if the original image is heavy on disk (say, a RAW), you can have as much modified copies as you want, as each one only take some hundred of k's.
