OO losing pictures
There have been many reports of OpenOffice files Writer and Impress (not sure about Calc), of all versions, suddenly losing pictures, and leaving only a blank frame.
I use the Xubuntu LTS versions, running usually the latest Apache OpenOffice, more recently the 4.5.0 nightlies. I have not used Windows since 2007/8, so cannot say if the following remarks have relevance to that version
LibreOffice have fixed the problem of picture loss, at a cost (from memory) of 44,000 euro.
I regularly make and re-edit Impress presentations, some of considerable size (~100+ slides, for later selection) and some of 10/12 years of age, and have found a method that seems to overcome the picture loss.
My files are stored on a network addressed storage; I have disabled "Save Autorecovery every n seconds" (entering 0); in more than 9 years of using that setting in OpenOffice, both in the creation and editing of large Impress presentations of 100+ slides containing images and also of several illustrated booklets, I have never lost pictures. Prior to disabling the AutoRecovery process, I regularly did lose images.
My guess is that the AutoRecovery process, when it happens, does not correctly preserve the existing OpenOffice environment, perhaps itself being interrupted by input keystrokes from the User.
I do not offer this as a sure-fire solution, but merely record my experience

With the amount of memory available on modern machines, there can be no objection to increasing memory allocation; that said, I don't think the picture loss problem relates to picture size, within reason - obviously there are extreme examples of gigantic pictures which will break any system.
I am aware that other users of experience have had the picture loss problem, usually on Windows versions; knowing some of these users and my own experience of picture loss I am reasonably certain that the size of pictures involved was reasonable; the picture loss appears to happen spontaneously: my limited investigation suggests, as I said, that it relates to AutoRecovery and possibly input during the AutoRecovery process by the User.
My standard procedure is to make a master file in Impress (note: not an OpenOffice Master File) with links to pictures of reasonably good resolution, and later downscale them, breaking their links by the Minimize Presentation process, the downscaling selecting such resolution as the target projector might require - higher resolution is now desirable for 1920x1080 projectors than for the older 1024x768 projectors.
My low level programming dates from the late 1970s/early 1980s, when I programmed in Z80 assembler and was then very conscious of the need to preserve the operating system environment around interrupts from peripherals. I would love to delve into the AOO source, but unfortunately have too many demands on my time to permit the study of C++ (which I don't know) and the navigation of the maze of AOO source code.
One suggestion I would make, both for AOO 4.2.0 and 4.5.0, is that careful attention be given to enabling multimedia - sound and video - integration in Impress. If a multimedia file (of most common formats) is playable at operating system level, then it should be readily insertable and playable in Impress.

Something like that...
I need to find the settings (again) and will open a Pull Request then...

Merged now in trunk and cherry-picked for AOO42X.

Thank you for sharing your experience!
A memory corruption may be the main problem, but pictures nowadays are
typically much bigger than they were, when OO was designed.
That said, I would like to increase the memory settings at least for
trunk/AOO42X.
Default is now:
Graphics cache: 20 MB, 5.2 MB per object, Remove after 10 minutes. 20
Objects
Opinions?
Regards,
Matthias
