This format is found in only one demo: "Tobias Richter Fullscreen 
Slideshow". The pictures are in an interlaced overscan format and 
use a separate palette per scan line (16 colors). The resolution of
the screen data is 352 x 278 pixels, with 176 words per line.
The files are packed with the Ice. The unpacked format is as follows:
 48928 bytes     screen data first screen
 48928 bytes     screen data second screen
  8896 bytes     color data first screen
  8896 bytes     color data second screen
------
115648 bytes total

The screen data is stored in 4 seperate bitplane blocks: first all data 
of bitplane 0, then all data of bitplane 1, then the data of bitplane 2 
and last the data of bitplane 3.
