Currently only 100 thumbnails are cached. I will look into changing this limit to be based on memory usage (pixmaps are stored by the X server, but they take memory nonetheless. A maximum size thumbnail (256px) takes 16 times more memory than a small thumbnail with size 64). To adjust the maximum limit, we thought of providing a slider for globally adjusting cache sizes in digikam. If you have a machine with 4GB RAM you easily spend a few MBs more for thumbnail caching than e.g. I do with my 512MB laptop.

The bahavior of greyed out thumbnails is unclear to me. Before first loading, the area is painted white. Before further reloads, it is grey. I need to investigate this.
