Sisyphos,

Try increasing your graphics cache.

You can find it in the options dialog under memory.

Also personally I do not insert draft images into a writer document then 
continue editing. Maintaining the source document, link and graphics 
program in memory while changing the image is just increasing your load 
and asking for problems.

You should edit your images directly. Turn off all the other programs 
while you are doing it. If you need to review what you are doing I 
sometimes create a PDF of the source document and review that - because 
the images are all compressed it occupies less memory.

Have you tried using the JPG format? Make you images twice the size you 
need them. Once you scale them down I promise you will not detect any 
difference between your TIFF or PNG files.
