This task summarizes proposed changes to the thumbnail storage (both images and video thumbnails).

Thumbnail size

This is currently a setting in kphotoalbumrc. By changing the setting outside of kphotoalbum (or by not correctly syncing the setting between different machines) the thumbnail database can become inconsistent and contain thumbnails of different size.

Proposed change:

Write the thumbnail size into thumbnailindex.

Note: video thumbnails need to use the same settings.

Video thumbnail storage

Is the current approach (10 thumbnail files per video, flat directory layout) becoming a performance bottleneck?
