Need your slides scanned in a specific order? Group them with rubber bands denoting the order to be scanned and our technicians will then scan your photos in that order. SCAN IN ORDER OPTION EXPLAINED: Choose this additional option if (a) you have bundled your slides into categories and they must be kept together. The number in the top right corner tells us the order in which to scan. If the bundle order is not important, we do not need the number there. We either follow the number in the corner or scan in random group order when no number is present.
