I was using custom directory ( img.sitename.com) to store all my images and set the path in media setting. The latest version of wordpress, I can't see this url path to set image directory. My current site is working, without any problem. I am wondering,
How can I set the image path in future? Is that URL setting changed to some where else?
I see few sites with jetpack activated and additional directory name in image URL like "i0.wp." Is this same kind of image directory? If yes, how can I customize it?
