Hi Dave, there are two methods for displaying pictures...
Method One...
scroll down till you see... "Manage Attachments"...click that and it should be self explanatory.
Method Two...
upload your photo to a photo sharing website such as
http://photobucket.com
Once you upload your photo to that site the URL will be displayed beneath the photo.
Umm, hopefully you didn't try mounting your favorite orchid that you only have one of on any camphor tree branches. I forgot to mention to only use "disposable" orchids when experimenting with different wood. All bark has some types of organic compounds and I really have no idea which compounds are unsuitable for which orchids.
