Problem with exporting calc sheet to pdf

I want to export one of my sheets to pdf. This simple sheet contains two images. When I export to pdf, one image stays correct, the other one is exported as zoomed in, which is not what I want.

While trying to resolve this issue, I noticed that the exported image in pdf looks exactly the same as if i would use the right click option “compress” (“comprimeren” in my language). So when exporting the image gets automaticly compressed, while the other one stays normal. is there a way around this?

Both images are quite big and had to be resized when added to the sheet, maybe this is important as well.

Solved! I needed to change the pdf export options from jpeg compression to lossless compression. Filed a bug report to change the standard behavior.
