Show various resolutions and instantly show the approximate size it will save as, so choice of resolution can be made.

Often when we save a file, we are forced to save at a lower resolution than we would like because of size restrictions for storage or emailing, etc. If we could make decisions based on being able to see the estimated size, we might be able to save at better resolutions than we currently do. The only other option at this time is to scan a document at a certain resolution and then decide if it is too large or not, and if it is, we have to rescan again, and again, until an acceptable size is found.
