Clickable Thumbnails. Are they gone?

[have_a_question]

After the introduction of the new code the clickable thumbnail option is apparently gone.

When asking the codes for each image, 2nd and 3rd options:

BB (forums) code:

and

BB (forums) full image code:

both produce the same code that gives a clickable full size image.

Is the option that produced a clickable thumbnail gone now?

How can we make a clickable thumbnail?

It is now working. See below.
