Hi, I need an user group to only be allowed to use gthumb and read from only one folder/partition which I will decide.
Please can you let me know how to do this?

Well, what you are asking is not as simple as you might imagine. To run gthumb you need to log in and run additional programs in the background, a graphical front end (X) at a minimum. You can use a minimal graphical front end such as fluxbox.
To be honest, IMO the easiest option might be to use the guest account. This has the advantage of being secured by apparmor, although it allows more access then what you want.
If that fails you can either use a custom apparmor profile or use a chroot/jail. These options will give you more control, but at the expense of you having to identify all the underlying applications and libraries that you need to allow to run a graphical front end and gthumb.
