My patch will probably be applied to gnome-settings-daemon after it 
branches for gnome 2.23. Thumbnails will be purged shortly after logon, 
and once a day after that.

Cool idea!

There is a complication, however: the thumbnails are stored using a 
hashed version of the original filename. It is not possible to tell from 
the thumbnail itself which file it corresponds to (one way hashing, in 
other words).

You have to know what files have been thumbnailed in order to delete the 
matching thumbnails.

That makes it difficult to create an elegant method of deleting 
thumbnails from a certain location.
