Images should have Locked Aspect Ratio
When I add an image to Power BI Desktop, the default setting is that the Aspect Ratio is not locked. This makes the process of scaling the image to a suitable size behave in an inconsistent way compared to (say) PowerPoint. If you turn on "lock aspect ratio", then the image scales correctly and consistently with other office applications.
Most images should be scaled with a locked aspect ratio.

Yes, PLEASE... this just makes sense.
I love the fact that Matt did this nice tweet to show the differences...
