SUMMARY

Folders show up to 4 preview icons to symbolize their content. But they exclude symbolic links to pictures.

STEPS TO REPRODUCE
1. create two new subfolders in folder overview: "copy" and "link"
2. drag'N'drop a picture on "copy" and select "copy" from the popup menu
3. drag'N'drop a picture on "link" and select "link" from the popup menu
4. refresh the view by F5

OBSERVED RESULT

Icon for "copy" features a preview of the picture inside.
Icon for "link" stays blank, even thought the picture inside can be shown fine via the link.

EXPECTED RESULT

The "link" folder shall also show a preview icon.

ADDITIONAL INFORMATION

If a folder contains other folders (or link to other folders), this is not really easy to show. I suggest, not showing folders inside folders. Instead subfolders can be indicated in the tree-sidebar as of bug 448132.

What is really strange is, showing e.g. a text file on the icon, to indicate, that the folder is not empty, but clicking inside, the text file is filtered by Gwenview, as it does not know how to display a text file. I would recommend having a consistent notion of what is shown on the icon and what is inside, if you open the folder.

This bug is for every type of file previews (not just pictures). When a file is a link, his preview is not used on folders.

Still present today :
Operating System: KDE neon 6.2
KDE Plasma Version: 6.2.4
KDE Frameworks Version: 6.9.0
Qt Version: 6.8.1
Kernel Version: 6.8.0-51-generic (64-bit)
Graphics Platform: Wayland

I am updating the name with "files" instead of "pictures". I tried to put the old name with pictures in the alias but it turns out that only words as alias can be put in it (it makes alias unusable to improve search).
I am also putting Dolphin as product instead of Gwenview.
