Lucone, thanks for your answer.
I have been experimenting a little and found out, that 768x980 seems to be the maximal resolution for a picture to show up without resizing. A fullscreen mode would be great not to waste 33012 pixels at the bottom...
Then I tried to convert a batch of pictures to png with irfanView. I got quite good results with the following settings:

Batch conversion:
-RESIZE: Set new size, Width 768, Height 980
-Preserve aspect ratio
-Use Resample function
-Don't enlarge smaller images
-CHANGE COLOR DEPTH: 16 Colors (Use Floyd-Steinberg dithering)
-OTHER OPTIONS: Convert to greyscale
Format: png, compression 6

Of course this doesn't crop white borders or split 2-paged images.

I put the images into a sub folder in the "Images" folder. Unfortunately the sub folder doesn't show up. Instead all images are in the root. The second problem is that switching to the next image using the side bar doesn't word. I have to exit to the images and select the next one manually.

I see, I have to do some more testing here...
