Question

.rwWindowContent, .rwExternalContent
        {
            border-style: groove !important;
            border-width: 1px;
            border-radius: 10px;
            background-image: url(background.jpg) !important;
            border-color: GhostWhite;
        }

as you can see in following Image all the styles related to Background has been removed by IE8 tool:

Is there any suggestions ??

Answer 1

make sure you saved you jpg in RGB mode instead of CMYK. hope this helps.

Answer 2

IE 8需要知道容器的宽度和高度（如果为空）。

Answer 3

I think better convert your image from .jpg to .png format. This may solve your problem.
