How can i set the alt attribute of all img tags in a page

trallon · Sep 28, 2006

Hello, how are you? I need to set a default value into all the alt
attributes in my pages (ie: <img alt="".../> ), I have web controls
that nor are developed by me and they write img tags in my page. I
think that using javascript I can do this issue, but ¿what is the
better way?
TIA, trallon

The best way is to put appropriate alt attributes in your code, either
manually (hard coded) or dynamically on the server. Putting an empty alt
attribute won't do any good.

http://www.w3.org/TR/html401/struct/objects.html#h-13.8

"Do not specify irrelevant alternate text when including images
intended to format a page, for instance, alt="red ball" would be
inappropriate for an image that adds a red ball for decorating a
heading or paragraph. In such cases, the alternate text should be the
empty string ("")."
