             Bug #: 46447
           Summary: Images disappear and corrupt Impress presentation
    Classification: Unclassified
           Product: LibreOffice
           Version: LibO 3.3.2 release
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: UNCONFIRMED
          Severity: major
          Priority: high
         Component: Presentation
        AssignedTo: libreoffice-bugs at lists.freedesktop.org
        ReportedBy: zeitlinie at yahoo.de


Since several versions, and also in previously used openoffice versions, and at
least for all 3.x versions I had, the presentation module Impress shows the
following bug which completely ruins any given presentation. This bug occurs on
a regular basis - usually once every presentation I generate:

For no specific reason, suddenly, images which have been embedded (not linked)
into a presentation 'disappeare' with only a 'missing-link' placeholder
displayed instead of the image in the editing mode of Impress.

Once this behavior occurs, the presentation is irreversibly damaged and is in a
state of unpredictable behavior.
In particular, the obvious first choice for a fix, namely to simply delete the
missing links and re-embed the images regularly leads to chaotic and additional
disappearance of more images in the presentation.

A minimalistic example of such a presentation, showing only one missing image
is attached.

The unpacked ODP files of such presentations always display the same pattern
regarding this issue:

In the unpacked file noLinkErr.odp without the bug
and in the directory 'Pictures' one finds the relevant image
"10000000000001F4000001F0BC3B6675.gif" in the present case,
while in the XML file content.xml one finds a markup which links to that image
<draw:image xlink:href="Pictures/10000000000001F4000001F0BC3B6675.gif"
xlink:type="simple" xlink:show="embed" xlink:actuate="onLoad">

In the unpacked file LinkErr.odp with the bug
the relevant image is missing in the directory 'Pictures'
and in the XML File content.xml the markup which should link to the image reads
only
<draw:image xlink:href="">

For me the only way to 'avoid' this error is to keep a long list of
incrementally saved backup versions of any presentation I generate - which is
very awkward.
