@George, nice site and colours. Though am a bit confused when people ask for opinions, are they asking based on the design ( graphics person ) or the code ( developers ) and functions?  I'm working on a catalgue system that can be adapted to almost anything and one of my targets is to get models on it. I'm signed upto various int'l sites that I purchase images with its copyright ratios for web or print. I see you have used images, how do you go about the copyright issues on these if the models are kenyans, which agency did you negotiate the rates with?
