1. Create a thread for every image you download from the server using -

[NSThread detachNewThreadSelector:@selector(downloadImage:) toTarget:self withObject:@"Image URL"];

1. Send a request to the server to retrieve the image using a thread block.

-(void)downloadImage:(NSString *)inURL {
        NSAutoreleasePool *thePool = [[NSAutoreleasePool alloc]init];
        UIImage *theImage = [UIImage imageWithData:[NSData dataWithContentsOfURL:inURl]];
        [self performSelectorOnMainThread:@selector(uploadImage:) withObject:theImage waitUntilDone:NO];
        [thePool drain];
    }

1. Update the image so you may view it. A view can only be changed by the main thread.

-(void)uploadImage:(UIImage *)inImage {
    [inImage retain]; // add image to View.[inImage relese];
}
