Got a tip for you. Use save for web on your scans. It lessens the bandwidth usage on both parties.
Actually, I'm using Photoplus for almost all my scans. Does it have a similar feature?
Well, I don't know Photoplus personally because I use Photoshop CS4, but if you save your black and white scans as png format, that'll shave off almost half of the scan's size.PNG is a format that employs lossless data compression.
