I have a mission for you. Make the set as wallpaper function of XnView MP work properly with Linux Mint Cinnamon.
You can even do these on your own computer, but it's a bit slower.

*************** CoPilot Question ***************
In the XnView MP application, installed on Linux Mint, there
is supposed to be a Set As Wallpaper function, for making an image
viewed in the program, to become the desktop wallpaper. This
function does not seem to be working. Is this failure a function
of the Linux DE (Cinnamon), or is the function simply not working ?
*************** CoPilot Answer ******************
**Short answer:**
The failure is **not CinnamonrCOs fault** - XnView MP simply does **not implement**
a working rCLSet As WallpaperrCY backend for the Cinnamon desktop environment. This is a known, confirmed limitation of XnView MP on Linux Mint Cinnamon. [Linux Mint Forums](

## WhatrCOs actually going on
### 1. **XnView MP does not support CinnamonrCOs wallpaper API**
Multiple Linux Mint forum reports confirm that:
- The **.deb version**, **Flatpak**, and **AppImage** all fail to set wallpaper in Cinnamon.
- The feature *does* work in GNOME, XFCE, KDE, and FVWM.
- The developer has not added Cinnamon-specific wallpaper handling.

### 2. **Cinnamon *does* support programmatic wallpaper changes**
Cinnamon exposes a simple gsettings interface:
gsettings set org.cinnamon.desktop.background picture-uri "file:///path/to/image.jpg"
Users on the Mint forum note that XnView MP could theoretically call this, but it currently does not.

### 3. **This is a known, longstanding issue**
Another thread confirms that the rCLSet As WallpaperrCY button and context menu in
XnView MP are present but **nonrCafunctional** under Cinnamon. Users have tried scripts,
.ini edits, toolbar buttons, and context menu hacks - none succeed because XnView MP
never triggers the correct Cinnamon command.

## So is the DE (Cinnamon) at fault?
**No.** CinnamonrCOs wallpaper system works fine:
- Nemo can set wallpapers.
- Pix and Xviewer can set wallpapers.
- gsettings works.
The only thing that doesnrCOt work is XnView MPrCOs internal wallpaper function.

## Practical workaround options
If they *must* set wallpaper from XnView MP:
### Option A rCo Add a custom "Open With" script
Create a small script that calls CinnamonrCOs wallpaper command:
#!/bin/bash
img="$1"
gsettings set org.cinnamon.desktop.background picture-uri "file://$img"
Then add it to XnView MPrCOs "Open With" menu.
### Option B rCo Use Nemo instead
RightrCaclick the image in Nemo raA **Set as Wallpaper**
This works reliably.

### Option C rCo Report it upstream
The Mint forum suggests reporting the bug on XnViewrCOs official forum,
since it affects all Cinnamon users.

## Bottom line
**The feature is broken in XnView MP itself. Cinnamon is not the cause.** Without Cinnamon-specific support in XnView MP, rCLSet As WallpaperrCY will continue to do nothing.
