Usability feedback please on unique photo gallery

Hi,

I’ve just finished this site and I would like feedback on how easy it is to use.

http://www.nzography.com/

If you mouseover the black square on top left there is a menu with a section for help if you cannot figure out the interface.

Please give me feedback on how easy it is to use the interface. Also let me know if you find any bugs or if anything doesn’t display properly.

I’ve heard from a few people that on some of the image sets that the first image does not load properly, although I have never experienced this myself. If you experience this or any other problem, please let me know. Also, I’d appreciate details about what browser you are using and what version of flash player you have installed.

Thanks in advance to everyone who responds.
