Great and useful plugin. 5/5. However, I just noticed that it breaks the upload new media window. I was using this to convert images that I had already uploaded so I don’t know how long this has been present or if it was working previously. Just a day or two ago there was a new WP update that might be related to this. Also, my host was going to upgraded PHP at some point to the latest stable version. I disabled the plugin and suddenly the upload window reappears.
