how i can add link in mediapress

While uploading status, users can only add Text, Image and links only.

i want to add link as well right now user can only add text and images so let me know which extension we can use Enable adding media through link? Yes
 No If No, It will completely turn off remote file and links features.Enable adding direct link to files from other sites? Yes
 No User will be add to remote files using direct url eg. http://example.com/hello.jpg i have done this setting but in the frontend it not showing

we get cloose option in while we update the post we belive this close is coming from mediapress plugin because while uploading the images we get the same close button
