JS error when percent sign used in image url in the Image Dialog

[Wiktor Walc]

This is rather a rare situation, anyway it seems that people are using placeholders for a directory where images are stored to replace it later with a valid directory. When placeholder contains a "%" character in it's name, IE is throwing a JS error in the Image Dialog (probably because it expects a correct hexadecimal value after % (?)). This bug exists also in FCKeditor.

Steps to reproduce

• Open Image Dialog
• Paste the following url:

  [%placeholder%]/file.jpg
  

• click on the "Alternative text" input element
• Result: JavaScript error (invalid argument)

Is it possible that we simply make no assumption on form of (no decodeURI) the image "src"? We're also not doing that for link elements. Thus it's possible for user to keep anything they want inside the url.
