I am struggling for several days with this problem I can not solve. All programs that use KDialog, specially chromium/firefox, don’t show preview of JPG files higher than 3mb in file size. As I need for work to upload high resolution images, this is getting annoying to open dolphin, check thumbnail and filename, then return to chromium(KDialog) and select the right file. I can see previews/thumbnails of image files below 3mb, but unfortunately most of my work relates to files with file sizes higher than that.
Dolphin shows all files properly.
I checked the file kdialogrc in /.config, but I see no option to increase file size image preview.
Is there actually any way to increase it to KDialog? Any help or suggestion? Lately I had to switch to windows in order to do the upload fast without switching windows and checking. I need to get rid of windows and delete that partition once and all, specially now I can use photoshop in a VM.
