@collini Definitely sounds strange! Must be something going on with your home computer… difficult to help without more information… just to make sure….are the images removed just like in your screenshot? “Background Images” unchecked, no images at all every time you open the .blend file? Or are the images still added, but can’t be seen?
I did a search online and could just find a few cases that seemed to be similar to yours. https://blender.stackexchange.com/questions/45024/packed-images-used-as-background-dont-show-up-when-reopening-the-file Maybe check this out…. something about Load Ui not checked in your preferences. So that the Blender user interface doesn’t remember that you saved the images.
