Okay, it does not work with Firefox 31.1.0 (on the desktop, not mobile- latest Suse). You cannot enter anything into the three fields. Joomla is 2.5.27

Also, the image insertion window does not have a place for the image link (only the image URL).

But, the latest version of Chrome allows text entry to the three fields.

Note that neither Chrome or Firefox allows you to dismiss the image insert window with "Cancel", you have to dismiss the window itself.

As entry of the image info is a one time event, I will just use Chrome for the moment.

I will check some other browsers and report back.
