How to change the link of an imported image file?

I imported the *.png graphic file into the LibreCad *.dxf file. After running the file on another PC I got a blank screen.
I know that Libre Cad doesn't save imported files, only their links. The question is whether it is possible to change the saved link on another PC? How to do it ?

It is not possible from within LibreCAD. You would have to edit the dxf file in a text editor.
But if you place a copy of the graphic file in the same folder along with the dxf at the new location it will be found despite the invalid link.

Thank you for the hint! I was able to change the link address in the dxf file using Notepad++
