For scanning photos to work in iPhoto08, what are the best options (let's assume I have a flat bed scanner with sufficient DPI). Although -- what's the best DPI for a 4X6 if I want to support blowing them up digitally later? Are there utilities where I can put multiple photos on the bed, and scan them at the same time, to chop them separate later? I have SOOOOO many photos, I don't want to scan them one at a time! Are there any services anyone knows about for standard photos to be scanned in high volume? These would be photos over the last 15-20 years. Any recommendations, utilities, strategies, etc. appreciated.
