Cannot find image link in forum

[Lowlander]

I uploaded the file prior to starting my post some day's ago, could it be too BIG.

You won't believe this but as if by magic the Image Box Icon has appeared bottom left of screen.

Thanks for taking the time to reply.

Edit,
When I clicked post, the Icon disappeared, that's OK as I am leaving the page, now I am in Edit post mode the Image Box is not available.
