There is a file upload option where you can upload/post pics with each post (however I have had some personaly feedback that this isn;t working for users - it is working for me so it will be a permission issue). I will look at it this week.
A Project Section where customer setups/projects could be posted is definately an option, however I think once everyone has access to posting/upload files/pictures in each post this could easily be done, while still remaining part of the site - as well as being listed in the search section.
I will have a look at Photopost to see what type of features it offers.
Thanks for the feedback!
