Question
I am trying to create power point presentation on the fly (without usage of previuosly created template slide). So far I have results, but experiencing difficulties on adding picture (see code below)
When disable the P.Picture part it is working (means the created pptx file can be opened).
With the P.Picture part PowerPoint proposes repair and removes "found non-readable part" resulting of showing only placeholder of the picture with "Picture can not be shown message". If you expand the pptx in unrepaired state the media folder contains proper picture that can be opened... _rels folder contains file that properly links the existing image file with the image placeholder... I am surely missing sth. but what???
Any help appreciated! Many thanks!

No correct solution
OTHER TIPS
My problem was really very simple - just found it comparing the repaired against genererated version (serialized XML)...
Unrepaired there was in the BlipFill portion the Prefix a: repaired p:...
There are BlipFills both in Presentation and Drawing
So my mistake was in using the D.BlipFill instead of P.BlipFill
Now it works as expected.
