My best wishes for News Years Eve!!!


When I take up a number of images, I experience that ALBUM Prievew panel does
not show Album Prewiew anymore. 

Only things I can do at this time is to select all Album previews again.

So, this Album previews seem to be "instable", somehow. 

This is true, even when copying the _complete_ folder with any related file to
another place (pics and DG-Databases).

?? Do I make a mistake 
?? Is there a related systematic database design-issue envolved?
?? Would MySQL be better as QSQLITE? 


Besides, and in contradiction, tabs can reliable be stored in single pictures
metadata, and these metadata are stable there. Independant from the very
storage location!

Reproducible: Always



Expected Results:  
Album preview take time to use. 
DK should NOT waste time of users because of double work.
