That's a beautiful invisible pipe if I do say so myself.
You can also use one of the many image hosting sites and just post the IMG code directly into the post box.
I have been smoking this beauty for a couple weeks now. I must say this pipe is a little harder to keep lit than my other pipes. She smokes great though and was worth every penny! I took her to the pipe club tonight and smoked some great 10 year old "frog morton on the bayou".
