I've been working as freelancer for some years before a multimedia company hired me. When I was freelancer the only thing I made where I actually sold all the rights was logos. If I made hompages (full sites) the only thing they owned was the fotoes if the company had supplyed them and the txt. They had the right to use everything else, they could change text and fotoes/pictures if they whished, but not the layout, colors and so on. The template was/is mine. This was offcuse for normal html/php, flash was another matter. If I was asked to do a picture or animation, I would never sell the contens so they could alter it.
