Try setting the width:6em (instead of height) and leave height:auto (or remove it as auto is default).
I know it is a little backwards to set width with a "height value" (em), but it works.

You're right. Completely counterintuitive but it works. Changed the em value from height to width. The images don't skew anymore when up- or down-sized, though 6em does not actually translate into 6 lines of text; more like five. Will tweak.

With black and white diagrams, the savings are even more pronounced than just these few color images (B&W/Grayscale/few colors compresses VERY well in PNG).
In this large project I am in the process of working on, I generated 175 very high quality (almost all were ~1200 px wide) PNGs of Tables/Charts/Diagrams. These compressed down to 9.10 MBs.
The equivalent 175 JPGs would be ~18 MBs (I just did a rough generation of JPGs from the original source). I could probably squeeze a few MBs out by optimizing the JPGs a little, but they will reach nowhere near 9.10 MBs.
JPG is a format built for "natural/photographic" images, and the algorithm is not the greatest when dealing with "artificial" type images.
When dealing with delivery fees and/or bandwidth costs for overly large book files, cutting needless MBs off of the book is very important!

It would seem the most efficient would be some vector graphic format for such items, but I don't know how well they are supported.
