I am copying the URL that Flickr establishes after I select BBCode and size option, I then open this forum ,type in a Post Name, go to the body of the post page and click on BBCode, I next select the Insert Image Icon from the page menu options and paste in the URL and click on create a post. The image is there as you can see but the description is hosed to say the least. BTW I am not using postimage.org at all.
Aha!!!! Did a little different and didn't have to edit anything except I wished the description was all below the image. I opened the reply page, typed in my comment's, paged down a couple of notches, pasted the URL in, selected BBCode then clicked on create post
Edit in: I just noticed something ,if I click on the word "Loquats" next to the image it takes me back to my Flickr Photostream and also if I click on "Sunset" next to the image in your previous reply it takes me back to your Photostream,,,,,,,,,,,,,,,,,,not sure if this is a good feature,whatcha think?
