I am sorry to say that there isn't. You can always request an email address in a PM (if the member's email address is not visible) and handle it that way. Or copy and paste the email address if shown and use your native email program.
Thanks, Peter. I ended up sending the photos via email.
Or you can post the images in a thread and share with all!
I would normally do that, but this was a response to a want to buy so that didn't apply in this situation.
