Export the image with relative path setting

It will change the relative image path to absolute path, when exports the Image Markdown to html by “Document - HTML” or “clipper – including style HTML”.
It will keep the relative image source setting when Exporting by “Clipper – without style HTML”.
I think it should be kept the markdown setting when export to HTML, and export style independent.
Example:
Md:
   

Export:

•   export to html file or Clipper-including style HTML

    <img src="d:\SVN\test\system/materials/block_Diagram.PNG"

• export to Clipper-without style HTML

    <img src="materials/block_Diagram.PNG"
