Life is hard. Tell them to make up their minds!
One thing you could do: highlight each thumbnail in the timeline that you need to change (or have changed). Then, under the Clips menu on the GUI, pull down the "Selected Clips" option. Now, only the changed clips will be on the timeline. Create a new Gallery still bin, then right-click in the Gallery viewer and "Grab All Stills", and now you'll have a bin full of just the changed stills. Select all those and export them as JPEGs and send them to the client.
These Clip sorting options are extremely useful. All covered in the manual.
