However, nothing I can do on the iRex DR800SG with the original or the beta firmware changes it's seemingly arbitrary handling of images in EPUB files. I get different image sizes based on my font settings even when CSS requests an image the full width of the screen. And then the images are always scaled somewhat.

I've attached a sample, ideally it should either be the full width of the display or 1:1. I can deal with either, but not whatever it seems to be doing.
I can confirm this. I couldn't get an image to display 1:1 even if I set No Margins and the image was the exact visible screen size (768x981). In that last case it was shrunk so that there was a quarter inch on each side.

Even viewing the raw PNG you can't get 1:1 unless one or both dimensions are exactly the visible screen area (either 768 width or 981 height).

Attached is the test pattern image from the original ePub pasted into a 768x981 white space image. It views correctly 1:1 viewed as a PNG, but if you put it back into the ePub it won't, even with No Margins selected in the Settings.

Also included is a full 768x981 test pattern so you can see that it fills (or doesn't fill) the viewable area.
