Regardless of the solution on which you ultimately settle, you may want to avoid churning out thumbnails on the fly every time they are requested if you are in a heavy load environment. This could be as simple as reading in the timestamps on the original image and the corresponding thumbnail, checking to see whether the thumbnail is "fresh", and updating accordingly. This won't be a big deal to you if you've got CPU and disk access to burn, but if these resources are a potential bottleneck for your services, then you should definitely do this, assuming that disk space isn't something of which you are apt to be in short supply.
