Hi I also had issues posting from Flickr, I found 'share' ' to
get the ' bb code' unreliable. (see my earlier quoted below).
[see Whitestone post, in this thread, 17jan21 so you know what correct bb code looks like including the bold bits are most import, something like :-
" https://live.staticflickr.com /xxxzz/xxxyz.jpg "
see my earlier post below.
(*I just checked and the share get, bbcode doesn't work for me. Hmm. I'm an android user. )
I now use Google photos the https://www.publicalbum.org/blog/embedd ... otos-image process, which Landslide brought to our attention. (this thread 12th Jan 21).
I hope some of this assists
Good luck cracking it
