When the picture is in PhotoBucket, left click on the top box beneath it which says 'URL'.
That will highlight it, then right click with the cursor in the highlighted bit and click 'copy'.
Then come into the BBS and type in a header:-
'Me'
Highlight the header and then click the icon at the top which looks like the Earth with a pair of goggles. This opens a box in which you paste the URL that you copied from PB.
'Me
Then you get the picture link.
