Version: unspecified (using KDE 4.5.3) OS: Linux I preferr using dolfin for organizing my fotos instead of digikam. It is just a personal preference but well it is this way. Dolfin does not reliably quickly load the image previews of files. For example, if I open my pictures folder it takes a while untill all files are previewed. If I change to a subfolder the same thing again. Then I change back up to the picture folder and all previews are loaded again. It does cache (I hope?!) but it still takes a lot of time until all pictures are loaded. Digikam does this just fine. No matter in which folder you change, if you have been there recently (or ever?) the previews are there instantly. It gets really frustrating if you organize your pictures in subfolders with date, event or something and you often switch between these folders. Reproducible: Always
Thanks for the report. Could you please give some more detailed numbers regarding "takes a while" and how many pictures the folder contains? A caching of the images is done already (not directly in Dolphin, this is handled in kdelibs in a generic way). I did some tests with image folders having around 1000 images and switching between 2 folders having 1000 images only requires around 0.2 seconds to restore the cached images. Please also give more detailed information which view-mode, sorting etc. you are using (e.g. is grouping enabled in the icon-view).
My screen is 1920x1200 thus there are a lot of images displayed at once. Icon mode with 64x64 icons, image previews enabled for all suitable formats and folder previews as well. There are 37 folders and 406 files on the root (with a total of 2583 pictures including subfolders) and 208 MB of files on the root (the size displayed in the status bar) 3,8GB in total. The most files are 2304x1728 JPEG files from my 4MP camera with an average size of 2 MB per file. When opening the folder it takes 3 seconds for all file previews and folder previews being displayed (only those displayed at once without the files only being visible when scrolling down, this naturally takes then longer in total) and almost two seconds when just refreshing the view. In digikam file previews take forever to load (much longer than in dolfin) but once they are created, they instantly(!) appear when opening a folder.
Addition: Disabling folder previews does not speed up the process at all. The folders and files themselves are displayed instantly even in my music folder with 1331 files (which did display a progress bar in earlier versions) but previews are still slow. :)
Thanks for the update. One minor thing: Does it take 3 seconds only when opening the folder the first time or also when e.g. changing to a sub-folder and going back?
Whenever I access the folder. No matter if the folder was opened the first time or just resumed to it. Only when refreshing (i.e. pressing F5) it goes a little bit quicker.
I just noticed, because I wanted to re-test a former bug I submitted concerning the text preview, that when I modify a text file and just press F5, the preview does not get updated (I added a new line break or some spaces into the file). If I navigate away and then back (no matter if a subfolder or parent folder) the preview gets updated to represent the current state of content. I thought this might be worth noting.

Resetting assignee to default as per bug #305719
Probably this bug was fixed too when https://bugs.kde.org/show_bug.cgi?id=393015 got fixed. Does this bug still applies with recent dolphin and KF5 5.45 or newer?
