No - I'm not sure what happened.
All I did was go to your photo account pull up the picture you were trying to post.
Right click on the picture and select "veiw image"
copied the url from the address bar
pasted it between [ i m g ] and [ / i m g ] (without spaces)
You get:
[img]http://gallery.pethobbyist.com/data/104168unagi2.jpeg[/ img] (without the space between the / and the img)
and voila

BTW she is a beauty!
