How to fix picture on the same place


I would like to ask, why my pictures do not stay on the same place on the backround? For example : my backround is a building and I placed pictures (and also topics) on the windows, but every time I open my presentation, these pictures are moved to the left or to the right.

Thank you very much for the answers :slight_smile:
