Thank you for the replies. About two hours after I asked, I discovered that jpg doesn't support transparency. I also learned I was doing something wrong in LibreOffice, and I can use png files. It wasn't wasted time, as I discovered a few tools in GIMP to remove the white box frame behind the image. Unfortunately, those tools washed out some white in the main part, so I removed the white background by hand.
There may be a better idea, but what I have now is working as intended, even if it took me three and a half hours.
