He's right. This sucks.
So let's standardise on MediaViewer/File: or #/image/File:
Personally I would recommend the latter for 2 reasons:
- It's good not to mention the name of the technology in the URL.
- In mobile we need the / prefix as we have urls such as #/editor - the initial '/' prefix helps distinguish it from any anchor element in the DOM since '/' is an invalid character.
If you are strongly attached to MediaViewer/File: please make a case. I am open to #/mediaviewer/File:
