MIDlet usually uses web image which can be get via
private String url;
private byte[] data;
private int datalength;
private DataInputStream dis;
private HttpConnection hc;
url = "http://xx/xx.gif" /* or "http://xx/xx.jpg" */
try {
hc = (HttpConnection)Connector.open(url);
datalength = (int)hc.getLength();
dis = hc.openDataInputStream();
data = new byte[datalength];
dis.readFully(data);
if (datalength > 0)
image = Image.createImage(data, 0, datalength);
}catch (java.io.IOException x){}</pre>
If the image object is created successfully,it can be displayed by usual way.
Such like in Canvas
<pre>protected void paint(Graphics g)
{
g.drawImage(image,0, 0, Graphics.LEFT|Graphics.TOP);
}
