I attached an example of how you can place a jpg image in the content of the RadButton. Let us know if this helped you or if your scenario is more complex.

Not sure if you are dealing with the current project here or with another one, but generally you should used Padding="0" to remove a gap between the Button's ContentPresenter and its boundaries. However same images might have transparent parts, or the WPF framework might not fill the Image entirely (pixel perfect) over its bounding control. That is why I suggest you to also try BorderThickness="0" on the button and also SnapToDevicePicels=True.
