ImageIO: Read JPG image from URL with header: referer?
 

Hi,

I'm trying to make thumbnails of some images on the net. So I though I'd use
the ImageIO library. But apparently it only has this method to read images
from the net: read(java.net.URL). But I need to set the header referer
property on the net connection before reading the image. Which I had done
before with the URLConnection object.

(e.g.
URLConnection urlConn = url.openConnection();
urlConn.setRequestProperty("Referer", referer);
urlConn.connect();
)

But ImageIo.read() doesn't accept URLConnection. What do I do?

There's also ImageIO.read(java.io.InputStream). I haven't tried it, but
I'd say the following should work:

URLConnection urlConn = url.openConnection();
urlConn.setRequestProperty("Referer", referer);
urlConn.connect();
InputStream urlStream = urlConn.getInputStream();
image = ImageIO.read(urlStream);

ImageIO.read(urlConn.getInputStream());

Works like a charm. Thanks.
