Trouble with importing and renaming images

Been using RoboHelp 2020 for several months now and after a little learning curve have started to like it.  

Having a couple issues:

1. Importing from Word

2. Renaming image files

The two issues go together.  I imported a Word document which had a lot of images.  When it was imported the images came in using names like Image1.png, Image2.Png..... so on.  The trouble was that the help system already had images with those names.  That was Problem #1.

So, I thought that next time before importing I would go through the help system's list of images and make sure none of them had generic names.  I tried it out on a couple of Images.  I went to properties and typed in a new name for the image.  The image was renamed, but the connection to the topic was gone.  

What's the best way to handle this? 

How can images be renamed and still maintain their references?  Note that the old (classic) version this was all done behind the scenes.  

Thanks in advance.....
