While I really like the photography, I find your site slow, unresponsive, and unintuitive. A few examples: the pages load invisibly, leaving me with just a black screen, which leaves me wondering whether it is working; the small image selection menu on the left is very jumpy and hard to pick an image from; selecting a caegory clears the right of the page, but the selction window appears on the left, where I am not looking for it.
My perspective is that a gallery like this should be immediately engaging and accessible, because I look at the various linked pages as part of a variety of links which come off of this forum and other places. If your site is taking up extra time, and not giving me immediate access to the images, I move on. Perhaps this sound curmudgeounly, but there are lots of time-consuming photographer sites out there that I have just passed on, because the page has dictated to me the speed at which I am able to look at the images, and I have a limited amount of time to see all the sites linked to on the various sources I look at. Were I alone in this, I would just admit to being a grump and shut up, but I know that many others have a problem with such flash presentations, and I thought I should say something. In fact, I initially closed the window with your site, after fiddling with it for half a minute, and only reopened it based upon the feedback lower in the thread. I am glad I did, as I really appreciated the images you posted.
A favorite piece of web-design advice I read was 'don't break the way people interact with the internet,' and I think that might be pertinent to your site design. I know I don't go to a new and unknown site with the idea that I am going to spend 10 minutes there, and see what happens--I look at it, and if it engaging, I spend longer--I feel that the site has a barrier to entry that makes me want to give it less of a chance, as I would have already scanned through half a dozen images in a conventional gallery in the time it took to load two on yours.
Perhaps I just come across as cranky and hurried, in which case you are welcome to ignore me, but I thought I would give feedback on the site. My feedback on the photos follows the praise above.
[Technical note: I am viewing your site on a iBook G4 running Safari, connected to a major university internet backbone, so speed of computer and connection does not seem to be the limiting issue, but I could be wrong.]
