When batch saving JPG images, is it possible to skip the confirmation prompt?
I need to modify several JPEG, JPG, PNG, and BMP images to 350 dpi and 200mm width, then automatically save them as JPGs with optimal quality (12) and standard baseline.
I recorded an action.
Then I used the following script to repeat this action. However, when encountering PNG files, the action halts and prompts me to save the original PNG. This is annoying since I don't need to retain the original PNG format.
Additionally, while newer Photoshop versions allow disabling saving as a duplicate, it sometimes still takes effect, consistently saving duplicates—which is also frustrating.
Another issue is that actions always save to the previous directory instead of the new file's location, which is equally bothersome.
Thank you.
