No, WML bad! For a midlet you read in the HTML, and there is an image tag <img src="http://www.domain.com/image.jpg"> So your midlet needs to read the InputStream from your http connection, parse the tag, get the image source URL, open an InputStream to the image data then load that into an image object using Image.createImage(<inputstream> ;
Then you can display the image object in an imageItem UI component.
