Thanks for the quick reply. I guess I didn't express myself well when
I used the word "versions". By versions I meant diferent
representations, like thumbnails, for example. Currently, I'm
generation them on-the-fly, but I'd like to keep then on the disk to
make use of Apache static file support.

Sorry about the confusion and thanks again for the reply.
