pres.Slides[0].Shapes.AddPicture(image);

pres.Save();

picture.png

Actual Result

The slide is empty.

Expected Result

The slide should display a picture shape containing the image from the file picture.png.

Discussed in #480

Hi,

I'd like to add a slide with an image, is it possible to e.g. add a new slide last in the presentation and then insert an image ?

I think the picture is added but either at a non-visible location or with a non-relevant size.
Changing size and location works.

Do you folks want to try this again? I cannot repro this on latest. This works just fine for me on latest master (0e5d22d). It's possible that this was fixed by fixing #671.

Actually now that I think about it, this is almost surely a duplicate of #671.
