Disabling lazy thumbnail generation

[ktosiek]

Is there a way to disable lazy thumbnail generation (and checking the disk for thumbnails on each access)? It turned out to be a performance problem for me when I need to return URLs for ~500 thumbnails in one request.

I've worked around this for now. It seems the only thing that really needs disk access is deciding if the file extension has changed from the original one.
