Choosing only a selection of String from BufferReader/downloading images

Question

I'm trying to write a program to download images from a webpage (basically it's a slide show, with links to the next/previous photo).. I am trying to automate it so that it will automatically load the next link, download the next image, until there are no more.. I haven't been able to find anything on how to download an image (jpg) to my computer.. and then I'm trying to figure out how to scan through the source code of the webpage, and choose only a selection of it (the link for the next page)..
For example, I'm trying to do this on this http://screenshots.teamxbox.com/screen/81845/XBlades/
Here's what I have so far--
import java.net.*;
import java.io.*;
import java.util.*;
public class Images {
    public static void main(String[] args) throws Exception {
         Scanner input = new Scanner(System.in);
         System.out.print("URL: ");
         String inUrl = input.nextLine();
    URL link = new URL(inUrl);
     BufferedReader in = new BufferedReader(
                    new InputStreamReader(
                    link.openStream()));
     String inputLine;
     while ((inputLine = in.readLine()) != null)
          if(inputLine.contains("http://media.teamxbox.com/games/ss/")){
             System.out.println("Photo Exists");
          in.close();
}If anyone could steer me into the right direction, it would be GREATLY appreciated. Thanks a lot!
I am willing to pay anyone who can help me figure it out.

Okay, let's take your original code. What's it supposed to be doing? Reading HTML from a web page? And you want to extract all the references to images in that HTML and do something with each of them? Okay. Then you need to parse the HTML and look for <img> tags and other HTML elements that refer to images. Extract the URL for each image. Probably it will be a relative URL, so you have to make that into an absolute URL based on what you used in the first place.
To download an image you use code much like what you have there, only you don't use a Reader because an image isn't text. Just use an InputStream by itself. You'll also have to look at the Content-type header to determine what type of image it is.
That should get you started. If you think it's too much work (and yeah, there's a lot of details to iron out there) then by all means go to one of the sites mentioned earlier to contract it out. But don't just mope around here pestering people to do it for you. Way too much work for a freebie.Thanks a lot man, I appreciate it
