Heavy pixelation in images

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!

Are you resizing on our site, or with a tool that you use before you upload? Our resize works, but if you upres (eg increase the size) of a picture very much it will cause pixelation and degrade the image quality. Even when using a professional image editing tool like Photoshop, you should avoid increasing your size more than 10% if at all possible.

No matter what you use, resizing will cause some image quality loss.

Your best bet to keep your image quality high is to set your scanner to output your scans at the size you want your pictures to be after you have uploaded them to us. Most scanners will let you set the output size. Be sure your resolution is 72 ppi for the output..that's the maximimum a browser can display..but smaller will look not so good.

FYI...the largest picture we store on our servers is 1024 x768 pixels...you can load images bigger than that but that causes our servers to resize them down automatically...so don't go bigger than 1024 x 768.

Here's a link to a pretty decent tutorial on all this http://graphicssoft.about.com/..._image_resizing.html

Hope this helps.

Thanks Tony.
What I do is resize with FinePixViewer the software that came with my Fuji camera. I select all photos and resize from 1280x960 to
640x480. Should I specify resolution ro sepcify ratio as it asks in the Batch Resize Images? It also asks for width and height pixels.

I need to start selling soon. Its been weeks and I can't get it right.

Thank you again,
Bob

If Finepix Viewer gives you the opportunity to specify resolution try setting it to 100. You may need to read the instruction manual with FinePix viewer and see what it says to do...I don't use that product so can't really give much help with its specifics.
