When fullScreenReading=true the following is added to the built-in KePub stylesheet:

img {
  display: block;
  margin-left: auto !important;
  margin-right: auto !important;
  width: auto !important;
  height: auto !important;
}

This has the bad effect of making images display centred on a seperate line when they should be displayed inline with the text of a paragraph.

The screenshots below show a book where the publisher has included an image of some hebrew letters (instead of doing a proper job and embedding a font containing glyphs for the letters) in the following way:

<p class="indent">It was quite by accident that Brother Francis finally 
discovered the pilgrim’s stone. While wandering thereabouts, he stumbled over the 
stake which the old man had driven into the ground as a marker. He found himself 
on his hands and knees staring at a pair of marks freshly chalked on an ancient 
stone: <img alt="image" height="15" src="images/Art_P11.jpg" width="18"/></p>

1. Unpatched, KePub, fullScreenReading=true
2. Patched, KePub, fullScreenReading=true


This patch disables that added style by replacing img --> _mg, so that images are displayed the same way in KePub full-screen mode as they are in KePub normal reading mode (and ePubs in both modes).

Multi-version patch, paste into libnickel.so.1.0.0.patch:
