What you could do is create an ';Action'; by clicking ';Window'; then ';Actions';. Click on the little arrow on the top right hand side and click ';New Action';. Perform your resolution change on the image, then click the ';Stop'; (square button on the bottom left of the actions window). Now your resolution change has been saved.



Now click ';File';, ';Automate';, ';Batch';. Under ';Action';, choose the action that you created. Choose ';Opened Files'; under ';Source';.
