Just to make sure. PGF is not a typo. This is about Progressive Graphics File. The creating of PGF files is out of scope of Dolphin itself, a general preview-plugin must be written for this. As we don't have a subsystem in bugs.kde.org for plugins it is fine to leave this open as wish for Dolphin. I just wanted to mention this because most probably reports like this will stay in the state NEW forever until any developer outside there will write such a plugin "by accident". Is there no possibility to share the handling of image files, i.e. reading the preview from them, creating thumbnails etc.? It seems duplicating work if every application codes that functionality just for itself. > Is there no possibility to share the handling of image files,

There is and it's the preview-plugins I mentioned above. I'm not sure why digikam2 uses a custom approach, probably they have good reasons for it.
Ok, I'll ask them and report back. digiKam use PGF image to store thumb in a dedicated database. wavelets compression is used to optimize space (typically size can be reduced by 3 or 4 instead PNG way defined by open desktop) Also, digiKam use DB thumb to support unconnected removable media. This is not possible with OpenDesktop std. libPGF stil under developement and included into digiKam core. We patch it as well and report bug to PGF team.
