Thanks. The bit I'm not getting is "You can then run your batch process against these".
OK. I have my images filtered for the label and selected.
Then on the top menu I choose Batch.. run Batch Process. The Batch dialogue opens. I have the Batch Process tab open. Then I have to choose a source folder from the file system and then a destination folder (optionally if I want save them in a different folder). At this point (last step) there is no connection between the source and the filtered images in the image browser. I am just choosing a folder and it blindly processes all files in that folder....
Are you 100% sure you can do this? (If so I'm going to look pretty stupid ).
