Heavy pixelation in images

Would appreciate help with photo imaging.
Scanning many books with pictures to list on eBay. Some color and some b&w. Printed pages too. Scans come out fine in computer but when I upload to Auctiva and preview, some are good and some pictures have heavy pixelation and the pirnt is grainy and blurry. I've tried to re-size but maybe doing it wrong. Very frustrating as it's keeping me from listing.
Thank you!
Bob
