1. No button for adding images appear
2. Even if one repair the php file then at least 5 more errors occur: cannot be used images that have been previously uploaded. New images are accepted only.
3. The description field works only if is filled up with an URL and not description
4. The option for Titles does not work.
5. The alt text as well.
6. And one more thing: It works under some old WP Themes but does not work under Twenty Thirteen for instance.
