I have always missed this feature since Netscape 3 was replaced by Netscape 4 and IE4/5. Where you could turn on or off image loading, and when it is turned off, a button is enabled on the toolbar that allows you to view the images on a single page by clicking it.

I agree. This feature is a must for any browser. IE 5 kind of has this w/ the load image option but there is no way to load all images on a page.
