There are two different ways images and shapes can be included in OOXML documents: VML and DrawingML.
The fix that I made earlier was related to VML. 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. There will be no fix in 1-2 weeks for DrawingML, I think full support for DrawingML will come out in March.
The issue is that when we started work on DOCX import, MS Word 2007 was saving OOXML files using VML by default, but now it seems to have switched to using DrawingML, possibly thanks to Windows Update and there are more DOCX documents with DrawingML appearing. We were caught on this because we were not planning on supporting DrawingML that soon.
