Correct:
Gecko and Safari 3 ignore the non-existing element-name "image" when it is used in CSS. These browsers
only use the correct "img" for styling the img-element.
Result: green border that turns blue on :hover.
Wrong:
IE win/Mac, Opera, Konqueror and Safari 2.x also apply styles to the img-element when the non-existing
element-name "image" is used in CSS.
Result: yellow border that turns red on :hover.
