External links show an icon, but no alt text is rendered. This should be added for accessibility.
Might be a WONTFIX, see bug 2443 comment 15
See this relevant discussion: http://en.wikipedia.org/wiki/Help_talk:Citation_Style_1#format_PDF_in_the_Template:Cite_journal.2Fdoc_examples I've changed the summary to be more specific, now that I've realised exactly where external icons are used: http://www.mediawiki.org/wiki/Help:Links#External_link_icons Alt text for them would be far more useful for screen reader users such as myself when they're used to denote file extensions, especially PDF files.
Note that there is now only one external link icon; however, as this is a background image it can't have an alt text set on it, so this isn't a trivial change.
Bug 54604 is a discussion on restoring icons.
