Some users, most commonly non-admins may encounter issues when trying to access SharinPix images. In such cases, it is advised to check the following:

• SharinPix licenses from the installed packages
• Profiles from the Albums Canvas App
• Profiles from the Visual Force security
• Abilities passed through the VF page
• SharinPix Permission Sets assignement

If you are using SharinPix from Lightning UI you can also check  the SharinPix Permission used.

For some extra features such as SharinPix Image Sync, the SharinPix Image Sync Permission permission sets need to be assigned to the required users.
