I have another problem on draftsight, when I insert an image .jpg (a cadastre), I don't visualize it in the model, on the other hand it appears in the print presentations, I don't see the reason, especially since it happens to me in plans .dwg which were created on autocad. Because when I do it on a brand new 100% draftsight or go say, it works well.
In short, not super disturbing but as I had gotten into the habit of always starting from an old file to have the hatching, blocks and so on available, I would like to find the solution, if you have it I'm interested.
I don't know if this can help, but it seems to me that Drafsight may have a problem with the address of the source. If your images are in the same directory, does it work better?
Maybe compare the file type of each (format). Because depending on the version of Autocad, some functions have difficulty working. look at the version or format of the recording when you save.
Thank you for your answers, I didn't manage to find a solution according to your leads, so being in a hurry, I remade a template for myself and it works.
