I can paste the image code from Flickr which does not display the picture. In preview mode the code is underlined and will display the pic when you click it. It’s been a while as I used to use tinypic but they are long gone. What am I doing wrong? 
Ive tried iOS with iPhone and iPad. Thanks.
Tim - Select the image in your photostream. Then click on the curved arrow at the bottom right. In the next window, click on the "bbcode" option then select the string in the text and paste it into your post. I select only the string between the first [url... and the first to keep some of the extra flickr text from appearing.
