1. Create The Image! I would recommend the size of 1080 x 1080 like the above default picture above! I checked the default source thumbnail when I refreshed my mod.

2. If you don't have thumbnail already in the mod root folder. Make sure to re-publish the mod.



3. Find your mod's root/folder by going in game and then clicking the "Open Local Folder" and look for thumbnail.jpeg right click on it and then edit using software like GIMP or Paint.


4. Once in editing mode, remove the image inside of the program such as Paint, Gimp, Photoshop. And replace it with yours.

5. Make sure to save/overwrite the new image

6. Now Very Simple, Go back into game, mods, and then publish the mod.

7. Should now look like something down below! After Publishing The Mod!
If not you will notice another thumbnail.jpeg image
