You need to upload an image somewhere, in order to obtain an image url. once you have the url, you can post it something like:

[_facebook requestWithGraphPath:@"feed" 
  andParams:[NSMutableDictionary dictionaryWithObjectsAndKeys: FEED_MESSAGE, @"message", 
        IMAGE_URL, @"picture", 
        LINK, @"link",
        name, @"name",
        description, @"description", nil]
   andHttpMethod:@"POST"
   andDelegate:self];

Note that the "picture" key is the actual url of the image, whereas "link" key is the url opened when an image is clicked.
