SMF Reply configuration

[Richard Crowley]

Now I am guessing because ... I cannot see the thumbnails while I am replying.

Yes, that is one of the unfortunate things about this forum.
Dunno whether is is a fundamental design of SMF, or just how this forum is configured?
In either case, pretty annoying. 
I have to open a second copy of the thread so that I can see the graphics in the previous posts while replying.

Just spotted what might help you Richard.
At the right hand foot of a thread is Quick Reply that just opens a text box and leave the thread as per normal view.

There's none of the normal posting/formatting tools available, just this plain box.
Just used it. :-)
