[MlMt] How can I set the width of an included image? (was wrongly: Plist confusion: How can I convert my binary plist files into the current default JSON-like format?)

[Steven M. Bellovin]

This is where sender-side scaling fails. Px—pixels—is dependent on the resolution of the recipients' display. Similarly, you can't use cm, because you don't know the size of the recipient's display. This is why the preferred width specification in HTML or CSS is as a fraction of the screen size (though even that has its challenges, if you want to handle phones and large desktop monitors—but a complete tutorial on how to do this with CSS is way out of scope for this list!)
