click on ur flickr link, then click on the image itself. in the bottom right of the screen, u'll see a curved arrow which represents the share photo
click the arrow, then select the BBCode
menu. choose the image size to share: i suggest either 800 x 450, which is within the large image guideline, or 1024 x 576, which must be cut down later.
one part of the image code starts with [img
and ends with /img]
. copy this code into ur forum post. when u hit the preview
button, u'll see the image embedded into it.
