Let them upload...
Lookatme™ provides controlled access according to strict privileges, to internal and external users.
Easy, secure access control is a core feature of Lookatme™.
Specific groups can be given access to contribute assets.
For example external contractors may be allowed to upload assets. Assets upload by the contributors go into a ‘holding bay’ pending administrator approval. Other users will not be able to access those images until they have been approved.
