Forum OpenACS Q&A: Re: A few questions about xowiki
Files and images are stored in the cr with a file: prefix. If this file is referenced via [[image:...]] it is rendered as image, in case it is referenced via [[file:....]] just a link is provided.
links to local labels can be achieved via [[#someanchor]]. The previous version required non-empty page names, now the page name can be left empty to refer to the actual page.
after getting the very last updates from CVS all the links to pages, files and images in other instances works perfectly!
i have not replied to another issue from your posting, about inserting anchors.
To insert an anchor in a page, one can use Xinhas InsertAnchor plugin http://trac.xinha.org/wiki/InsertAnchor without adding it in plain HTML. To refer to an anchor, one can use the wiki-notation as shown above.
