In Imageshop we have 3 different user types. If you don't use the front-end upload module you only need standard user and administrators. 

Standard user:

- A standard user only has access to the user interface (Front-end). They can view photos, download and have access to all front-end features. An administrator can decide which interfaces the user should have access to if you have several interfaces. 


- An administrator has access to admin and will have the ability to upload, tag images, delete images, edit categories, edit users, etc. An administrator will also have access to the front-end and have the ability to use all functions there as well. 


- Editor users are used if you use front-end upload. This is a special user who can approve images that standard users upload in front-end upload. They can also upload photos themselves and use all functionality in front-end.
