When default images in the image gallery and floorplan are removed, the user will no longer be able to add a new image. The 'add' button will become unclickable in these sections.
As a workaround, the user will have to:
  1. Set the draw to multiprize (if it is a single prize draw)
  2. Delete the current prize from the draw
  3. Add a new prize
  4. Set the draw back to single prize (if needed)
