Can I recover pictures in PP shown as white boxes with red cross

[Cambdoc]

Some of the imported images in Powerpoint are shown as white boxes with a
small red box at the top right hand corner. This has happened since I backed
up my data with a Western Digital synchronisation programme.
Any ideas if I can recover the images?

Cambdoc,
You are talking about a tiny little red x in the top corner and not the
large one all accross the picture?
If the former it means that PowerPoint can't find the source image. The
image you inserted was linked and shifted or deleted afterwards so
PowerPoint can't find it.
Reinserting it should fix it.
If the latter see here:

Cambdoc,
If you apply an animation to the empty box you will be able to see at least
the name of the picture, not the full path unfortunately.
Before I forget, also have a look here to possibly retrieve the link:
