Site Critique

my site
Installed the software from Alex’s wp-plugged download to get the wp-photos plugin. It is running on a linux box. Hacked the wp-photos plug-in to provide a simple “slide show” feature. Not being too familiar ( I know enough to be dangerous) with php I am not sure if the “hack” is very “clean”
I also modified the “default” style CSS to allow for the text to “wrap” the photo thumbnails.(sometimes I think I have too much time on my hands).
I am interested in other bloggers who use their blog to inprove the marketing of their small business; How is the blog used, what is included, what is not included, etc.
Thanks in advance for any suggestions.
