I uploaded a .jpg to my web host using the editor, Insert Image button.  It was loaded successfully and now I want to run a test in prep for setting up a process for the user.

I want to now delete the uploaded image file using the editor.  I don't see a Delete button on the Insert Image window nor does a highlight the filename/click the keyboard delete key work.

 

 

When I upload another image file which has been renamed to the one I want to replace on the host, the editor says that the upload was successfull, but the image does not change on the host. 

 

What am I missing?
