Hi Gerard -- File insertion into Reply has no interface

Hi Gerard,
   My monitor does not display any means for inserting  a file or anything but text into a reply. 
   Here's a screen shot of your Reply.  I can only add text to the empty box.  There are no icons, menus, or anything else to start off the process of adding a JPEG file.
   What am I missing.

It's also difficult to add text after an inserted file.  It takes a lot of trial and error to get past the inserted image.

I use Windows 7 and Internet Explorer.
PP:  What file size in pixels by pixels should I use for an uploaded JPEG file
PS: Is there any way to get single spacing when hitting ENTER.
