A document with an object element in an image map. The object element embeds an image in PNG format, and contains an img element with the GIF version of the same image. The alt attribute of the img element identifies the image and conveys the same information. However, the alt attribute of one of the map's area elements is empty. The object element does not have a title attribute or any other text alternative, so the only text alternative to the image is the alt attribute of the img element nested inside the object element. Alt attribute for areas in client-side image maps: object and nested image both referencing same map Christophe.Strobbe@esat.kuleuven.be en Copyright BenToWeb 2005-2007 2005-08-29 accepted QA How to specify alternate text General Inclusion: The object element How to create client-side image maps Client-side image maps: the map and area elements

This test case is intended to fail because one of the areas of the image map has no text alternative. The empty text alternative is an issue in itself, but, in addition to this, browser support for the object element may also determine if this test case is accessible or not. Internet Explorer has weak or no support for the object element.

Scenarios in this test case need a new question!

There are three areas to the image, does each one have a description (this is separate from the description for the whole image)?

The image has a fallback with a text description but one of the areas in the image map has no text description.

The object element has an img element with an alt attribute as a fallback . Since there is no direct text alternative, it is not entirely clear if this code is accessible. However, since the second area element in the map element has an empty alt attribute, this case does not pass.

This test case is identical to sc1.1.1_l1_011, except that the second area has an empty alt attribute.

(In Mozilla 1.7.3 and Firefox 1.0, the map does not work if the map element has only an id and no name attribute.)

(Internet Explorer 6.0 on Windows 2000 does not support object but displays the fallback image; Internet Explorer 6.0 on Windows XP does not display the fallback image. Firefox 2.0 and SeaMonkey 1.1 do not display the fallback image if the image defined by the object element cannot be retrieved.)

This test case does not map to a WCAG 2.0 technique or failure.

The image has a fallback with a text description but one of the areas in the image map has no text description. User testing with screen reader users provided the following results: most users of speech output (20 out of 22) could understand the image, and most users (3 out of 4) of a Braille display could also understand it. (All were users of Internet Explorer 6 or 7.) User testing with magnification users provided the following results: one user of Internet Explorer 6 could understand the image. (Only one user of magnification for this test.) This test case needs re-testing with a new question in the scenarios.
