I'm using 2.2 on a bunch of sites, and have this problem only on one host. When I upload an image, it does not show the size/link radio buttons and the "send to editor" button. Instead the url for the image is shown, and two other fields with html code that can be used to insert it into the post.
Is this normal behavior? Does it have anything to do with the crappy host the site is running on? It's a fresh install of 2.2, not an upgrade from earlier versions.
