Links to images don't work if redmine is not installed in web root dir
Encountered issue
I installed Redmine as a Bitnami Packaged app. Because of the way that Bitnami configures the installation, Redmine does not run in the web root (i.e. http://my.site.com/) but rather in a subdirectory: http://my.site.com/redmine/).
In this configuration the various icons on the Kanban board are not displayed. After installation of the Kanban plugin, they end up in: http://my.site.com/redmine/images/ but the generated html page expects them in http://my.site.com/images (which does not exist).
As you can see in the example below, the url for the arrow_down.png is not correct. It points to "/images/arrow-down.png" but should point to "/redmine/images/arrow-down.png".
An excerpt of the Kanban web page source code:
<div class='sortable'>
<a title="Nach unten" rel="nofollow" data-method="post" href="/redmine/redhopper_issues/move?id=1&target_id=2"><img src="/images/arrow_down.png" alt="Nach oben Pfeil" /></a>
Expected behavior
Kanban plugin icons should be displayed in the web page.
Steps to reproduce
Install redmine in a folder other than the web root. Install the Kanban plugin and open the Kanban page. Arrow icons etc will not appear.
Workaround: Create a /images subfolder in the web root and copy all the .png icons from the /[redmine subfolder]/images directory.
