Aha,

Join www.tm-img.com (started by a fellow TM member, Gambalunga, and administered by two members).
Then follow the instructions at https://www.tm-img.com/page/ifu

That should allow photo posting.
A couple of years ago when the forum was suffering significant slowdown photo upload to TM was effectively withdrawn, so Peter (Gambalunga) did some excellent research and started the photo hosting site for us.
I should perhaps put a request in to Simon (Talkmorgan) to remove his earlier instructions as they do cause a lot of confusion to those who are not aware of the changes of a couple of years ago.

If you fail with TM-IMG, send me a PM.
