Hi,
Firstly, did you try using other browsers? did you try clearing cache ?
secondly,
Navigate to the sys_attachment table and navigate to Configure > Security Rules
In the next list you have all the access controls available to execute the CRUD for the table. Group by Operation and focus on the READ ones
Create a new Access Control on READ similar to the next image
This will allow people to see any image or attachment used by service portal instances in general
About access controls..
- First of all you can release/restrict content so be very careful or you can show something that user are not allowed OR hide something that they can see.
- In order to create Access Controls you need to elevate your role to security admin
Mark my answer correct & Helpful, if Applicable.
Thanks,
Sandeep
