When an image is unavailable - for whatever reasons -, then its alt text should be rendered inline and use as much space as it requires: the user would certainly want the image placeholder to expand as required to render the alternate text. "The reader of the page frankly couldn't care less if the author has made a mistake and the page is not completely available. The reader wants the information. So if an image is not available, the page should adapt. This is what alt text is designed to do."

" 4. For an object (e.g., an image) with an author-specified geometry that the user agent does not render, allow the user to configure how the conditional content should be rendered. For example, within the specified geometry, or by ignoring the specified geometry altogether. " Techniques for User Agent Accessibility Guidelines 1.0 2.3 Render conditional content (P1) Example techniques This is exactly what this bug report is about: to ignore placeholder dimensions for image and render alt attribute value as inline. There is also a setting in Internet Explorer 6, Internet Explorer 7 and Internet Explorer 8 which was intended (and was supposed) to do this: Tools/Internet Options.../Advanced tab/Accessibility section/Always expand ALT text for images regards, Gérard
Duplicate of bug 48458 ? --------- Firefox's implementation: browser.display.force_inline_alttext Boolean True: Force broken images' alt text to be displayed inline False (default): Show an icon if rendering in Quirks Mode and there is no alt text, or if rendering in Quirks Mode and the image has a size specified. http://kb.mozillazine.org/About:config_entries#Browser. What that also means is that, by default, the alt text will be displayed inline whenever Firefox is triggered in standards compliant rendering mode. regards, Gérard
