CSS advice for Image scale mouseover/mouseout event

Hi,

I'm trying to add CSS to an image to create a mouseover/mouseout event. I just can't seem to get it to work.

I wan't the the scale of the image to increase to 1.5 on mouseover, then return to 1 on mouseout.

Any advice on the CSS coding would be greatly apreciated....

Also how would I make an image hover whilst mouseove?.

Thanks, Mike
