Normally when you want to download a picture or a file in some website using Browser, you send a Http request to the server, and the server returns back a response. The browser reads the content from the response and ask you where to store the download content by popping up a 'Save as' window.

For your program, you just open a connection of a certain URL and try to write this connection information to somewhere. What you need to do is to fake making a http request to the certain URL ,catch the response and extract the response content to output to somewhere you want. HttpClient can help you to do that.
