I like that lightweight scheme Dan,
(My reply is about your presentation, not about your images. Was that your aim Dan ? )
I'm mulling over possible gallery options for my own stuff - but what technology is that on yours, if it isn't Flash?
(sincerely sorry if I'm missing something obvious. I don't use the heavyweight web-authoring tools)
On the ergonomics and navigation; when the time comes when you've got multiple themes and/or dozens of images to show, do you plan to let us skip rapidly among the images rather than only one at a time ? My preference is always to know where I'm 'sitting' in long sequences ...
But, Flash or not, I like it ...
