Does not show media image after the add Url

Unable to get the image size. Please fill in the following properties manually. If you leave the fields blank (or 0 for width/height), the plugin will try to resolve them automatically

shows width[] height[] text fields

once I click Add, it created linked object (no thumbnail image), when I tried used that in the post, it does not show the image.

Would have been great tool if it works.
