Improve miniature generation

Issue description

In larger systems with lots of photos there is a miniature generated. It seems currently to be the case, that this is done for all photos as there is timeout requests popping up when the miniatures have been deleted due to free disk space. This beats the purpose as the disk space is quickly occupied again.

Developer comments

The OCR no longer uses the largest miniature. This made it possible to not create it at all for file topic types where it is no specifically declared (Display original instead of miniature). For any file there is now only the smallest one (2) and one of the larger ones, either 3 or 4. This frees large amounts of disk space.
