So pic8 uses other image hosts. One of them is run by me. You'll see it come up as jssocial.pw. It allows you to keep history. The interface is like catbox plus history. You can find the image host at https://jssocial.pw/app/upload. As for deletion. The backend supports deletion but it isn't in the user interface. But the user interface of jssocial is user defined (the point of the site), so you could make a fork of the upload app that does have a delete button. It's designed so you just #import another app, and then overwrite whatever function you want to with a simple function declaration. The app name is the user name you develop it under. So the code for the upload app can be found at https://jssocial.pw/u/upload (the user page of the upload user).
