PowerPoint 2013: Images in presentation disappear – and are replaced with ‘The image part with relationship ID rId2 was not found in the file’
TRTRogersIL asked on May 7, 2013See post history
I’ve used PPT for 20 years and started using PowerPoint 2013 through Office 365 2 months ago and this has happened to me 4 times.
1. I create a presentation (Using copy and paste and/or insert to include pictures and other images)
2. After working on the presentation for a while I save the file and realize all the images (except smart art) are gone and replaced with the message above.
3. I have reinstalled PPT 2013 and it happened again. I have documents that are 50 pages long and have had to insert new images (Hours of lost work) then 3 days later it happens again.
Not sure if it is related but I’ve noticed that once in a while when I try to save a document (Happens in Word and Outlook Calendar items) it tells me the file is locked and makes me save under a new name.
First, make sure your copy of PowerPoint is up-to-date with all patches/service packs etc.
Do an Office repair:
Control Panel | Programs & Features
Select Microsoft Office
Click Change on the bar at the top of the file list.
If you’re offered two different options, try Quick repair first.
If that doesn’t help, try the more extensive version.
And in general, avoid (like the plague) editing files that sit on removable storage, in the cloud or on any drive or folder that’s being “watched” by automatic backup services. Put the file in a folder
