Invalid XHTML 1.0 strict

Is there a way to add an "alt" attribute to the captcha image (even "captcha image", anything)?

The reason is this causes an error in the W3C HTML Validator (http://validator.w3.org/):

Validation Output: 1 Error

1. Error Line 90, Column 206: required attribute "alt" not specified.

…img src="/image_captcha/1923236675" />

The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.

Typical values for type are type="text/css" for

and type="text/javascript" for . Any help would be appreciated – if there's a solution then I will be happpy to make a patch Cheers– :) Scott
