Aspose Words 5.1 Losing Images on Covertion from Docx to Doc

I am trying to save a .docx file to a .doc file using the latest aspose words.

To test this I searched the web for docx files and found the one attached (you will need to rename it).

However when I convert it for some reason it looses the images.

Is this a limitation of the current version?

Thanks

Hi
Thanks for your request. There are two different ways images and shapes can be included in OOXML documents: VML and DrawingML. VML images and shapes are supported by Aspose.Words in DOCX files. However, DrawingML is not yet supported. We are still working on DOCX import and that includes supporting DrawingML. I think full support for DrawingML will come out in March-April.
Best regards.

Thank you.
