Yes, you can use the IMediaService.Find method
This method takes an MediaItemFilter as parameter and it's Filter property is a MediaItemFilter instance
that has a Url property. Set this to the Url of the image and it will filter out the item that the url belongs to.

Media is retrieved using for instance MediaReference. But is there some way of retrieving a media from the URL that is used to access it? By URL I mean the value of the URL-property in the Media class, for instance server//imagevault/publishedmedia/something/something.jpg
