I don't know if it's possible but GIMP is able to receive command line arguments, so why not? Basically, I want to create a batch (action, macro or what it may be called) and then set up a cron job which will run every hour. So, it would be something like "If an image is in X folder, then resize, watermark & move it to Y folder"
Is this possible? If so, is a tutorial or a previous thread available? I can't find one yet.
