File with images that disappeared
While editing a presentation, sometimes images disappear and are replaced by 'empty images'.
Here's an example file, the empty images were originally drawings from the gallery, but this happens also with bitmaps.
They disappeared at some point while editing the document.
Hope you can do something with the file.
The problem is encountered by ours users on a regular basis.

bureautiquelibre: meanwhile, you may also give a try to last stable LO version 4.3.4 (instead of 4.2.6).
