“Skipped file” error
Sometimes it may happen that you will get an error saying Skipped: File already exists:
The reason for the notification Skipped: File already exists is that a file with that same name already exists in the output folder. So instead of overwriting that existing file, it just skips processing the file instead.
You can either move the existing files from the output folder to a different folder or rename the image that you want to process.
