First read the previous post.
Looking at your other posts to get the context, you are running into PDF issues. 600 ppi is a suitable value for printing an image of a postage stamp but not for a poster. Probably 200 ppi is more suitable.
However, I used 300 ppi in the video demo, I would not go above that.
The procedure is
Make a new empty canvas at the required size and ppi
Drop your image into it (or copy/paste if you want)
Scale that to fit
Export as a PDF
...and that gets you a large PDF
For a smaller PDF file size use ImageMagick http://www.imagemagick.org and a command
about 5 minutes https://youtu.be/TysvSEfd-is there might be something in there that helps.
