I believe these reports are converted from HTML to wiki markup using some kind of processing script.
Unfortunately, the syntax used by the banner generator for the game is not compatible with the wiki. If it were, then you could just convert the banner's relative URL in the report to an absolute URL for posting on the wiki.
http://battlemaster.org/testing/banner_image.php?shape=pie&color[]=red&color[]=green&color[]=green&color[]=red&color[]=red&color[]=green&color[]=green&color[]=redThe "[]" characters in the URL do not parse correctly on the wiki, and result in a broken image link. Maybe they could be replaced by the appropriate HTML character entities? The conversion script could do that. Or Anaris could change his banner generator syntax.
