In previous versions before Umbraco 7, there was an image link on the Media properties tab of an uploaded image. If I remember correctly, you could use that to identify the image and use the upload "Overwrite" option to directly update and overwrite an image. This was useful to switching out an updated logo (or other site images) for the site Template without having to do a bunch of copy and paste.
Is there a easy way to do this in Umbraco 7?
