RE: thumbnail generator

I would say on upload you make the sizes needed once. Why constantly resize
for each page load or on initial view / load check to see if its been
created if not create it. But as for performance I have no proof to say
which is better.

Is it better generaste image on the fly or when uploading we resixze
to some thumbnail size and save the image to be loaded later..

How about the performance issue if the site in full load..any experience so
far?
