Requires iOS 5 or newer
Image Grabber is the ultimate image extraction tool for iOS.
This tweak integrates with every web view, allowing you to grab the images you want from any Web page or PDF file !
(By 'Web page' I mean any kind of Web content, and you will probably be amazed to find out how common it is for iOS applications.)
It provides a nice popover-style photo browser with options to Save, Mail or Copy the selected image.
You can configure various aspects of this tweak to exactly fit your image extraction needs.
Some of the applications it works with are: Safari, Mail, Facebook, Twitter, iBooks, AppStore, iTunes and more.
Configure options from Settings app
