I’ve been playing around with ArcWeb Public Services and the different formats that can be returned (svg, swf, jpg, or png). SWF is the default image format of the map, but how does it compare to png? Take a look below at the same map returned as both swf and png.

Besides the smoothness of the swf image, the acetate point label has a nice background on it compared to the PNG image which just places the text on the map.
