Hi all
I want my program to get number of images from the web

http://www.url.com/img99.jpg
What should I use in order to read images and save it to my hard drive?
URL url = new URL("http://www.url.com/img01.jpg");
InputStream is = urlConnection.getInputStream();
something like that?
but it does not work and I don't know how to "convert" inputstream to file....
Please help!
