  Thank you! I agree with you, although it is not intended so.
  The other approach is more elegant, but I need also sorting as you have described. Perhaps some combined solution would be better.
  Still, being a QT newbie, I have no clear idea of the complexity of sorting for the other solution. Would it sort each time it looks for the next image? Would that cost? I'm running a big number of images, around 6000. What do you think?
