I will try to avoid any discussions about the logo in this thread
The proposal of website is nice, clean and simple, spontanously I like it. I think the grey and strong orange fit nicely toghether.
The only remark is that I would leave the byline "software by Pierre-e Gougelet" out. Eventhough Pierre is de facto the creator, I consider that kind of information to be less necessary. It should be under a "About XnView"-tab (not "About Pierre"). Alternatively it could be located on the front page included in the short text row stating "XnView is a free software to view, organize ... ... ... created by Pierre-e Gougelet".
My main argument for this is that the majority of visitors will probably only be interested in the software, and its features. They are probably not so much interested in secondary information, like who created the software, why and when it was made, what toolkits were used or how many rows of code were used and so on. All that is for a "About XnView"-section, for the ones who wants to know more.
I hope that I'm clear that I don't want to take any credit from Pierre, but to focus on what information the average visitor will want to see.
