i'm trying to add alpha effect for my image. the image is in rounded corner rectangular shape. i know there is attributes to change the alpha in CSS3, but i'm trying to be compliant with the w3c standard, which is still CSS2.
Sorry i didn't state my question correctly ealier. i was trying to change the alpha when i hover over the image using CSS2. i'm thinking to use the "background-image" for 100% alpha, and use the img tag for the 50% alpha. is there any better way to do this?
