I think you have to write "<cms:contentshow />" instead of
"<cms:contentshow element="Image" />".

The element "Image" in the "news" structured content type is of type
"OpenCmsImage" which is a nested structured content type that has an
element also named "Image".

In your XSD you are defining an element "Image" of type
"OpenCmsVfsFile" which is a simple type so "<cms:contentshow />"
should be sufficient to iterate over the images of your content.

I hope that helps.
