Joy uploaded them with the captions "Photo courtesy of Rhododendrons Direct. Used with permission." If they used your images without your permission, please contact them. If you would like, I can remove the images or change the caption to credit you in any way you prefer. You can contact me privately if you prefer by clicking on my name to go to my profile and then sending me a t-mail, private message.
(I removed your email, never a good idea to post those in a public forum)
