Missing thumbnails

[Gilles Caulier]

Hi,

Which kind of image format is affected with the thumbnails lost ?

Thumbnails are stored in a dedicated sqlite database and compressed in
Wavelets format (PGF). Did you have enough space on the disk where the
database is stored ?

How many items do you have in your collections ?

Best
