Anyone who appreciates anything about web accessibility knows that images need alternative, or perhaps ALT, text assigned to them. This is due to screen readers can’t understand images, but rather read out loud the alternative text message assigned to them.

Various other web developers just leave out the ALT option for spacer images (and perhaps other images).

Bullets and icons
