I made this test site trying to figure out how to use Image Ready. If i export the roll-overs from photoshop as gifs with dithering and manually make the page all in dreamweaver, there is no issue. But when i use IR to make each bolt a layer based slice with a roll-over state, and add the glow to the roll-over state, this is how it looks when i 'save optimized as'.
Ignore the regular state as I fixed that problem in a newer version, but the roll-over is what I need help fixing. Its supposed to be a glow like here (this was made integrating the background as part of the image, which makes it load very slow)
