Why are you even using two different images instead of using “height=# width=#” to scale the larger image down to fit the older format?

That's what I'm scratching my head about.
Use a high resolution source image if you can (300+DPI).
Example:
1200x400
1. Scale the KF7 version down by some fraction width/height:
Code:
<img src="example.png" width="600" height="200" />
(so it looks okay on a Kindle DX, etc.)
2. Give the KF8 and higher the original resolution (or % width).
Code:
<img src="example.png" width="100%" />
<img src="example.png" class="fleuron" />
<img src="example.png" />
KF8 can still handle the higher resolution images... there's no need to try to create some sort of "middle resolution" image.

Amazon is
recommending using at least 300DPI images or higher, where possible...
Like the fantasy map examples JSWolf always talks about. These publishers should insert the full resolution map in the ebooks (or at least 300DPI), not give us some low resolution, scaled-down, pixelated, unreadable mess.
As jhowell quoted above, high DPI will allow pan/scan, and actually be able to read the higher-quality maps (even if the image is larger than the device screen itself).
But there's no way they can make that mandatory. There's too many books out there (like book scans) which don't have such high resolution source images.
Again, it seems like a
recommendation, and letting you know what's possible with Enhanced Typesetting, not a requirement.
