Thank you Guys. There´s actually no Image, except for those simple portraits of Friends, that I wouldn´t contribute to what you´re planning to do. I´ve had many requests like that, but you seem trustworthy. I´ll have a look at my stuff and contribute whatever I think, fits with your Psychology topic...
As long as it´s a non-profit thing, and the artists get mentioned somewhere, you´re free to use any of the following contributions.
