I have an image that Libre Office pdf export can not handle without horizontally stretching (distorting) it out.
The exif data shows everything is correct and the image fits within the page limits.
problem 1) I would live to upload the picture for others to view but I don’t have 3 points ? WTF is that?
problem 2) the captcha keeps converting to Italian even though English selected.
You could upload it to a share (like https://filebin.ca) and post a link here.
The points are awarded for good questions, good answers (when someone upvotes it), and accepted answers.
The issue with wrong capcha language annoys many, but admins still haven’t fixed it 
Thanks, I’ve added the picture to filebin in this link.

This is what happens to me every time I export to pdf. The picture distorts and I can’t figure out why.
I’m using a jpg compression of 84% to keep the project file size low. This is the only picture affected.
Oh. Is this an answer to your question? 
The “Answer” is for answers, you either should had edited your original question, or use “add comment”
I see the image. But I don’t see the document that you are trying to export, nor the PDF that has the problem… I’ll try to do what I can to reproduce, but don’t know.
As expected, I see no problem: PDF
What is your LO version? (I always ask that, because people keep using an older version, and don’t try newer to see if that fixes their problem)
it first happened in version 4 something, and still does ion 5.3.3.2
I’ve also tried changing the image to a bitmap, tiff and png and a screen shot and exporting it to pdf does the same thing. I have uninstalled, reinstalled LO so many times I just don’t know what it could be.
