I have a website (www.designyourdecal.com) where I make custom decals for people. I made a "check out our work" page so that customers can see decals I have made. What I would like is for any of my viewers to be able to go and upload photos of decals I made for them so that everybody can see my work. Is this possible, and if so whats the easiest and simplest way for the viewer to do so? (It would be great if there was just a button the viewer could see that said "Upload your pictures here!") THanks!!

You would have to create admin users for each of your customers you wish to be able to upload images. You can create a special album for these uploads (if you wish) and give the customers rights only to this album.
