Publish a Dashboard - user can't see a banner

Hello,
I done a Dashboard with and image as a banner and it is working very well in “My Project” folder. But when I published it, the user could see this banner. How could I fix this issue?

Thank you in advance,

I can’t know for sure, but I suggest that you check the user’s permissions to read that shared folder.
