Help needed for downloading the image from Inage URL

Question

Hello everyone,
I need some help regarding setting a timeout for dowloading image from image URL
Actually I have a hash table with set of image URL's...
for example:
http://z.about.com/d/politicalhumor/1/0/-/6/clinton_portrait.jpg
which gives a image.
for(Enumeration e = google_image_links.elements() ; e.hasMoreElements() ;) {
                                  //System.out.println("final");
                                   //System.out.println(e.nextElement());
                                   try{
                                        System.out.println("Images download started....");
                                        //System.out.println(e.nextElement());
          //imageio is the BufferedImagereader object     
                                           imageio = ImageIO.read(new URL((String) e.nextElement()));
                                        image_title = created_imagepath +"\\"+ array_words[i] + counter_image_download + "." + "jpg";
                                        img = ImageIO.write(imageio,"jpg", new File(image_title));     
                                        imageio.flush();
                                   }catch(Exception e1){
                                        System.out.print(e1);
                                   if(img){
                                        System.out.println("The image " + image_title + " has been saved to local disk succesfully.");
                                   counter_image_download++;
                              }//end of for loopi am using the above code to download all the image from the Image URL's that r present in hashtable.
The problem i have been encountered with is...
Some URL's does not return any bytes, The code is not totally broken. In such cases, my code is hanging off at that particular URL and waiting to get some output data from the URL. The execution does not proceed furthur But if the URL is a totally broken link, the code is throwing an exception and I am able to handle it successfully.
But in the case of partially broken links, I am not able to go furthur because the code keeps waiting to get some data.
So for this reason I want to setup a timer and tell the code to wait for 5-10 min, in that time if it does not get any data, proceed furthur to download other links...
Please tell me how can I do this.. or plzzz tell me an alternative...
Please help me ans its a bit urgent plzzzz.
Thank you,
