I can't believe that a 1000*1000 image looks the same full-scaled on a proper inkjet a4 or letter-sized printout. The recommended size for a4 is 2362x3543 (for a 300DPI resolution) - and there *are* people out there who (mis)use Impress as a photo album. > If you agree with it, I think the next step is to find how and > where to descale the high-res image. > When inserting it.
