Hi Daniel,
We are in fact happy to take suggestions. Without feedback, the plane crashes. Same here!
The photos have been chosen by me and the structure of the front page will evolve. There is actually such a lot to do. I simply explore the portfolios of some and know the work of others. That is how pictures get on the front page. They just represent the breadth of OPF interest. If someone submits their pictures that is appreciated, however they may or may not be chosen. We are trying to balance out styles and areas of interest. So now, for example, product, classic portraits, editorial or news photography images are needed.
btw, I now see your real name and it is not Dazaau! Could you make sure you are registered under that very respectable name of Daniel Harrison. Get Michael Tapes to help you or, if you PM ore email me, I'll pass it on to him.
Asher
