I am still fairly new at Infragistics gauges, but... I have five "custom" gauges on a web page... three radial gauges and two linear gauges.  Everything works fine on the computer in which I am developing, but when I publish the page and view from different computers, I have a problem.  This web page has a graident fill on it, so there is not a consistent background.  These gauges have a backcolor of transparent, but I still see the box that would be the gauges background.  I am using version 8.1.  How do I correct this?

 Actually it is this way with the two charts I have on the page too, so I am sure that I am not setting some kind of property correctly.  I just don't know which one.

This seems to happen on IE 6 but not IE 7.  Does this have anything to do with IE 6 not supporting PNG transparency?  If so, I will need a fix as many of our customers will be on IE 6.

yes, this is because of IE6's lack of support for PNG transparency.  the simplest way to avoid this is to set a BrushElement for your root gauge, e.g. ultraGauge1.Gauges[0].BrushElement = new SolidFillBrushElement(Color.White);

that way the image will be generated with a white background. 

to actually get partially transparent images in IE6 is a little tricker...tony lombardo describes one method on his blog:
