That export field contents can be done from a script that loops through the records of your found set to export all the images to a specified location all in one go.
This will export the images to your desktop. Variations of it would export to other locations:
#Perform after you have found your records
Go To Record [First]
Set Variable [$Path ; value: Get ( DesktopPath ) & YourTable::ImageName & ".jpg"]
Export Field Contents [YourTable::YourcontainerField ; $Path ]
Go To Record [ next ; exit after last ]
This script assumes that you have one image per record, that each record also has a field that can be used to uniquel name the file and that all of the images are JPEGs.
