Historical tech post: Bugs I have seen - MSIE6 and replacing innerHtml with images (01 Feb 2007)

A table cell with an ID can have its innerHtml replaced by Javascript, without a page refresh. But if the content is img HTML markup, IE6 does not automatically download the image. If the image is already cached, it works sometimes. The general solution was to switch to an AJAX technique, which really does download the image.
