They did not give a reason, just referred me to a faq.  The only thing I can think of is like someone said,  noise, but I use the equipment they refer to, and I didnt have any postwork taht I remember on the shots..   so who knows...  I think I would rather just have my own site, see if I can make it known and just sell when someone is compelled to buy.
 
http://www.chuckcondron.com is the site.  I do not have every shot up just yet, nor a add to cart...just a simple site...
