A little more information would be helpful.

Are all the barcodes the same encoding?
Are all of the images the same direction?
What is the file type used to store the grayscale image?
Are all of the files of the same type (.jpg, tiff, png etc?)
Are the images clear / consistant between light and dark?

Are the original paper copies still in existance?
How many (approx) of these bar codes do you have? (hundreds, thousands, millions?

Enjoy!
