How do I see the logos that have been added to a .dwg file

I have a printed copy of the .dwg plan of an event site layout from 2019, I also have the .dwg file but when I look at layers using Draftsight (which is was originally created on) the company logos I can see on the print out are just white boxes on screen. What do I need to select to see and update these or is it like .ai where they are additional files that need to be linked? Thanks
