Can you share some screenshots of the error message you are receiving? Just trying to make sure I’m interpreting your issue correctly as there isn’t currently an option for uploading files for use as dashboard backgrounds.
The file upload feature built in to SharpTools is only for icons for dashboard tiles at the time of this reply. The Theme editor supports three options for setting a background:
- Editor Picks
- Bing (Image of the Day)
- Media URL
- You would need to have the photo hosted online somewhere (eg. Imgur)
