Do this:
做这个：
NSString *imgSrcValue = [self.webview stringByEvaluatingJavaScriptFromString:
@"document.getElementByID('yourImgScrID').value"];

What you want to do is parse the HTML for tags into an array, then extract all the src links into a new array (do this to avoid including other src tags for things like scripts). Bear in mind that some may be ".../image.png" so you will have to convert them into "theWebsiteYouWere.com/browsing/atTheTime/.png"
