[IDEA] Thumbnail Image Quality

[christopherr]

There are some inconsistencies in the folder ownership:

Code:

drwxr-xr-x 4 root staff    4096 Nov  5 07:46 imagesw

 but 

Code:

drwxr-xr-x 2 root root  172032 Nov  5 08:47 thmcache

Could it be related to the issue of not being able to remove the images?
