I thought this would be simple. Turns out, it is not.

I am looking at an image in the browser - I have tried Firefox and Konqueror.

I drag the image to the desktop. A small menu appears asking giving me: Widget -> Icon and Wallpaper -> Image as two options.

If I select Icon, it produces a small icon on the dosktop.

If I select Wallpaper, nothing happens!!

How do I get this simple thing done?

Help us to help

Your plasma version ?
(KinfoCenter - https://www.kde.org/applications/system/kinfocenter/ will tell it )

When you drag&drop - Is there error messages in the .xsession-errors ?

At here

Plasma 5.6.3

Drag&drop is not working from the browser to the plasma (wallpaper) desktop.
A workaround is to drag&drop to the Dolphin or to the Folder view widget and then d&d from the Dolphin to the plasma desktop.

Here are the last few lines from .xsession-errors:

Error loading plugin "kcm_fileindexermonitor" "The shared library was not found."
Plugin search paths are ("/usr/lib64/qt5/plugins", "/usr/bin")
The environment variable QT_PLUGIN_PATH might be not correctly set

Lastly, web browser to dolphin to desktop works withour errors.

There are several older (plasma4) bug reports:

- Bug 300984 - Click-dragging remote images to the desktop and setting as wallpaper doesn't work: https://bugs.kde.org/show_bug.cgi?id=300984
- Bug 306996 - Drag and drop of wallpapers does not work if the image is remote (job fails): https://bugs.kde.org/show_bug.cgi?id=306996

Maybe it is still broken ?

Looks like it is. I will mark this question as answered.

But it is quite sad that a DE as capable as KDE makes it so hard to set desktop background.

By the way, is there an application or a widget that will do this for me? I mean, I click on a button and it fetches a random pic from select images sources and sets it as a desktop background?
