Right - thanks Gilles! So to me it seems that it does not preload when
"Embedded preview load full image size" is set in the "Album Settings".

Details: 
- Folder with 4 raw images: IMG_1939.CR2, ..., IMG_1942.CR2,
- album view 
- then press F3 (to preview  IMG_1939.CR2):
  
  digikam: IMG_1939.CR2 : RAW file identified
  Running RAW decoding command: kdcraw -c -v -h -w -a -H 0 -b 1 -q 0 
                                       -o1 IMG_1939.CR2
  Running RAW decoding command: kdcraw -c -e 'IMG_1940.CR2'
  Using embedded RAW preview extraction

  # Is there any preload done here? 
  # I.e. should there be a kcdraw -c -v .... IMG_1940.CR2?

- Page Down:
 
  digikam: IMG_1940.CR2 : RAW file identified
  Running RAW decoding command: kdcraw -c -v -h -w -a -H 0 -b 1 -q 0 
                                       -o 1 IMG_1940.CR2
  Running RAW decoding command: kdcraw -c -e 'IMG_1941.CR2'
  Using embedded RAW preview extraction
  Running RAW decoding command: kdcraw -c -e 'IMG_1939.CR2'
  Using embedded RAW preview extraction

If "embedded preview load full image size" is not active, I only
see the kdcraw -c -e '...' commands (and just 4 of them), and that's it.
