-(void) webViewDidFinishLoad:(UIWebView *)webView { 

UIGraphicsBeginImageContext(CGSizeMake(webView.layer.frame.size.width, webView.layer.frame.size.height));
[webView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();


UIGraphicsBeginImageContext(CGSizeMake(70,100));
[image drawInRect:CGRectMake(0, 0, 70,100)];
image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

//image is now a 70x100 thumbnail. make sure you include CoreGraphics
