Do not use this plugin! It may appear to work at first, but if you check your website almost daily like I do you will find it starts to break your images, for example today, my logo was broken because this plugin broke down (after I spent advertising money directing traffic to my site), I didn’t even use up all my credits. I have found this happens on my clients sites as well, for no reason at all, images served through short pixel one day and working, give a broken link the next day.. and when you inspect element, the image path is through short pixel.. I may have forgiven it once, but this has now happened at least 4 times in the last 2 months.
