Check out NSURLConnection. I would better suggest use the ASIHttpRequest library for downloading the images from a url.

You will have to do the following:

1. Create a NSUrlConnection and implement the delegate methods
2. Pass the url in your request and you will get the data in –(void)connectionDidFinishLoading:(NSURLConnection *)connection
3. You can then create a UIImage from this data using
   UIImage *image = [[UIImage alloc] initWithData:activeDownloadData];
