Thanks guys for your suggestions!
Indeed flash site might have some drawbacks, that's why I'm preparing separate version only for mobiles (right now it's very basic) I hope that will solve the problem, at least for now.
Amazing pictures and a really nice clean and vibrant website. I also love the slight pan in effect on the photos when you select a new category. The main site loaded in about 3 seconds for me so no problem there. Levi must have been trying to load it on his Atari.
