Brightening an image using styles or Javascript

Question

I would like to brighten an image on my webpage on mouseover using css or javascript. Ive seen some examples using opacity and filters in styles but they dont seem to work for m

Answer 1

I would use something liek:

  filter: alpha(opacity=80);
  opacity: 0.8;

As far as I know, this is the only way to accomplish it in CSS. Is that what you are after?
