I'd also say that adding alt will be of limited to no use to users affected by low contrast, i.e. sighted users with images turned on. A tooltip showing the alt/title can also not be relied on, as users with a pointing device may not have a reason to place their pointer over the image long enough for the browser to pop up the tooltip, and users navigating via the keyboard don't currently (as far as I know, anyway) have a way of getting titles to display at all (and also, the image would obviously need to be in a link or other "tab-able" element).
