Thumbnail from NSURL

I am loading files that are downloaded from the web in a UIWebView (HTML files).

Is there a way to create a UIImage from an HTML file located in the Documents folder?

The goal is to auto generate thumbnails without needing to manual create them...

Update
My train of thought would be to do something in the line of:

NSString * s =  [[NSBundle mainBundle] pathForResource:@"test" ofType:@"html"];
UIImage *image = [[UIImage alloc] initWithData:
                                  [NSData dataWithContentsOfURL:url]];

Which of course does not work in this case!

Thanks!

S.

I found this solution here

UIGraphicsBeginImageContext(yourWebView.bounds.size);
[yourWebView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *resultImageView = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

resultImageView will be an image that contains the render of yourWebView.

If you want to shrink it down to a thumbnail size from there, I like Trevor's UIImage category for that purpose.
