I have 50 000+ images.

Do you have existing thumbnails ie. is there a need to recreate them?

I run on Core2Duo ~2.6GHz, 2GB of RAM

I like the idea of generating thumbs in the background, but it
shouldn't disturb normal usage
- the UI should load first before starting to generate thumbs
- thumbnail generation should have lower priority than the rest of processes.

After the thumbs have been generated it's great to browse photos, but
trying to do normal stuff on computer while thumbnail generation is
running is a pain. So I either leave it running when I'm not using the
computer or I stop the generation.
