I want to display a .jpg image in the UIAxes of the App Designer and then be able to click on certain pixels and save the coordinates to select a region on the image.
I know that this feature was missing in early 2018 but I couldn't find anything else on the topic.
Can anyone tell me, if it's possible to do and how?

You can use getpts to get the coordinates of the selected points but it is not recommended.
In order to select a region from an image you can use on of the techniques present in “Region Of Interest”
The techniques can be found at the below link
For more information in getpts refer to
Hope this helps!

App Designer supports Window button up, down and motion functions. See the "Window Functions" section here:
This post shows how to get the coordinates in the axes coordinate space
