Minor patch to fix two more instances (1.33 KB, patch)

Description Alan Barrett 2004-09-19 16:21:36 UTC
All images that are used as part of the user interface should have 
sensible alt text.

Example 1:  In the enhanced recent changed display, when there are 
several changes to the same article, there's an image of a blue triangle 
pointing to the right; clicking on the triangle invokes some javascript 
that changes it to a blue triangle pointing down.  I think alt="+" and 
alt="-" would be appropriate here, but both images currently have 
alt="".

Example 2:  In the 1.4 software currently installed at test.wikipedia.
org, redirects are displayed using an image.  I think that alt="REDIRECT 
" would be appropriate, but the image currently has alt="Image".

I suppose all this should be customisable via messages in the MediaWiki 
namespace, but sensible hardcoded alt text would be better than the 
non-sensible hardcoded alt text we have now.
Comment 1 Rob Church 2005-08-30 04:11:10 UTC
Agreed, it makes sense to have useful alt text.
Comment 2 Michael Zajac 2006-08-01 22:39:18 UTC
"This page redirects to " would be better alt text for the example.  Unambiguous plain English, normal capitalization.

Minor patch to fix two more instances

The two complaints in the first comment have been addressed.  Grepping for
"<img", I only found two that didn't have alt text, outside of the parser
tests; one is in config and the other is in Exception.php, so they're both
borderline trivial.  Any others?
Comment 4 Robert Leverington 2006-11-26 18:16:33 UTC
Just one extra thought, the powered by icon currently uses the alt text "MediaWiki". 
IMO it would be better to use the text "Powered by MediaWiki" as that is what the 
icon reads and "MediaWiki" would make no sense to someone who is using a screen 
reader or has images disabled.
Comment 5 Aryeh Gregor (not reading bugmail, please e-mail directly) 2006-12-22 20:32:46 UTC
A couple of tweaks in r18502.  All interfaces images now seem to have
appropriate alt text.
