Hi Enzee ...
I have created a photo gallery via Flash please look at
www.therainbows.net/photo it is only a demo so it is not the completed version but you should get some sense of what it can do. And more importantly it is more secure than the HTML site what you have. for example anyone could right click and copy a photo from your site.
I have many examples of what could be done if you want to revamp your site. and it is very much less that what you think !!
thanks
Darren
