Hadn't checked while busy doing other stuff but see the thread took off while I've been away. First off, Helen has been very helpful in moving things along with my request for photos of the cameras. Second, I don't believe it is unreasonable to request photos of items in the $2000 and up price range. I understand not every item can be individually photographed, especially when dealing in the tens of thousands of items that a business such as Adorama carries but it certainly wouldn't hurt to have a pricing cut off point where items are at least shown 1 or 2 pics of for potential buyers.
As noted above; it isn't physically possible with the way the website is configured to do this; but most times there is no more than a 36-business-hour turnaround for images requested by email.
