Has anyone run into this kind of result? If not, I need your suggestions anyway.
See attachment. Notice the cloudy lighter-colored-than-background streaks across the backgrround and the grirl's cheek. They show up in a jpg file like this, and in a tif. They show up at different scanning dpi. They show up in each of 4 different viewers. I cleaned my scanner glass on every surface I could reach thoroughly. The marks are not in the original 8x10 commercial photographic print (Walmart's) from which I made the attachment. (I don't know if Walmart's used a conventional or digital camera. The print was made on an 8x10 sheet of single weight (quite thin--it passes light very readily) printer paper but I don't know if it was done digitally or with a conventional chemical process. The marks did not show up in another 8x10 photograph nor in a 4x6 photograph that I scanned. The picture was made only 2 years ago.

HELP, PLEASE, PLEASE!
