Hi Jingrui,
Are you trying to use the System.Image entity directly? You should try creating a new entity, and make it a generalization of system.Image instead, also ensure the new entity has user roles and security configured for your user role.
Kind regards,
Ryan Mocke
Hi,
In System module check the security, if User role is there or not. If not add the User user role and update the security accordingly.
Hi Jingrui Zhang,
Did you check “User” user-role access in Project-level security?
Thanks and regards,

Ryan is quite right to point out that you probably need an entity that has been generalised from System.Image.
There are more details on how and why you need to this in the documentation.
