Dynamic Way to Check for Broken Image ALT tags on Site?

Question

Is there a website generator that can search for a given URL and output the urls where the images are missing their ALT tags?

Answer 1

Why don't you use W3C Validator?

Answer 2

Yes - use the w3c markup validator. It will output an error for <img> tags that do not have the required alt attribute.

Note that this will only happen for doctypes which require the alt attribute. I believe that, at minimum, all XHTML doctypes require it, so if your page does not already have that doctype, you might consider adding it temporarily to use the validator.
