Scanning a photo is easy but scanning from a book is tricky as the image in the book is made of lots of dots in a pattern. When you scan, this dot pattern can cause nasty patterns to appear in the scan. Many scanners will have an option to reduce this effect usually called "descreen". Sometimes changing the scan dpi up or down can reduce visible artifacts too.Another way to get a decent image is to scan at a very high resolution (600dpi or more) and then use a "gaussian blur" operation in a photo editing package. Alter the blur size until dots blend together and the pattern just disappears. Then size the picture down to a web-friendly size.</blockquote>
