no.

i use lynx here. it doest display images. this is why modern html requires authors to use the alt-attribute. html is a text markup language and not designed to be exclusively rendered with graphics. also, html says a user agent should simply ignore tags it doesn't know/can't render.

therefore, technically html-mails that rely on images (especially if they're not providing alt-descriptionns) are a bug. not displaying the images is a missing feature, in mail clients, browsers and anything else that renders html.
