Having read all that from everyone.. I'll contradict the lot of you and general DTP advice. (snigger snigger).. /me watches all the DTP pros turn away in disgust. I get large resolution images from Renault press service as I do the a car club magazine for Australia. Some of you might of seen it. One screenshot is use on the Qt Cool Apps page. These photos I get are usually a few mb large and up to 3000+ pixels wide, sometimes at 300DPI. As I live in Luxembourg now, I have to send the PDF from Scribus to the printers in Sydney so the size cant be too big. I resize in Gimp to the frame size I want and make sure DPI is at 300. Because the images are so large originally I still get excellent printed image quality after resaving as JPG. Sometimes I use PNG.. rarely use TIFF. Even Peter recognises these images turn out well as I know he has tested every Scribus produced magazine I have done with PitStop and on the Fiery he has access to. But I like to break the mould a little.. no need to be normal all the time :) Its good to keep the printers on their toes. Dont read this as a "use JPG, use JPG" email.. but given the right source images with high resolution, it is still possible to get them to come out ok.
