- [[Image:Example.png|thumb|150px|center|Text with [http://google.com link]]]
This results in a thumbnail with a caption of Text with link, and "link" links to http://google.com.
- [[Image:Example.png|thumb|150px|center|[[Text]] with [http://google.com link]]]
This results in a thumbnail with a caption of Text with [http://google.com link, where "Text" is an internal link
to the page titled "Text", and "http://google.com" is a bare
link to Google's home page. Also, with "]]]", the first two
brackets are parsed as the image's ending delimiters. The last
"]" is rendered as plain text.
The only difference between these two is that the second
example contains an internal link. In the second example, the
caption should be displayed as "Text with link", where "Text"
and "link" are linked appropriately. With "]]]", the last two
brackets should be parsed as the image's ending delimiters.
This bug should be reproducible on any Wikimedia wiki. I've
also tested it on MediaWiki 1.6.10, where the same
behavior is exhibited.
