I've searched and I've searched. But I have no patient with it. I have to try out the different modules and so on before I know if it's good enough.

Anyone who knows how to get these kind of functions on my site:

A list of pictures with prices underneath them all. When a guy with permisions is on that same side, he sees something different. He sees the prices/values in a box and he can easily change them. He presses update and it's done. There has to be categories too, and ways he can edit it and add more easy and painless. There shall be a lot with permision, who can edit. I as administrator shall could choose who is and who's not.

Anyone know that type of module or anything else I could use semilar to what I descriped, or could make me something as it.. Please let me know.
