If you have ever had trouble saving images from a Web site in Mobile Safari or a PDF file (such as in iBooks), then a new jailbreak tweak dubbed Image Grabber
by iOS developer Nikos Lykousas
should be in the middle of your cross-hairs right now. Image Grabber allows you to see every image in a Web site with the tap of a button and then you have the ability to do things with any of those images, but more on that later. As the screenshots above illustrate, the interface is beautiful and it allows you to navigate through each of the Web site's images one by one until you find the one you want. This tweak works even when a Web site has safeguards to prevent you from saving images.
In the screenshots above, you will notice a new button at the top left-hand corner of the Mobile Safari Web browser that reads, “Grab Images.” This is the button will you tap on to reveal the Image Grabber interface. The button does not appear automatically to help keep it from invading your Web view. To make it display, you can scroll all the way up to the top of the Web page and make the URL bar visible. At this point, the button will appear and tapping on it will open the interface you see in the screenshots to the right of the first.
From the Image Grabber interface, you will notice some buttons at the bottom. The X button closes the interface, the arrow buttons allow you to navigate through the images in the Web site (you can scroll through them as well), and the last button is your action button that will let you do things with the image you pick. The action button’s functions are shown below:
Tapping on the action button reveals a prompt asking you if you would like to save the image, copy the image, e-mail the image, or cancel. Saving the image puts it in the camera roll with the rest of your photographs, copying the image places it in the iOS clipboard, and finally e-mailing the image will launch the Mail application with the photograph automatically attached to your draft. The cancel button closes the prompt, but not the entire Image Grabber interface.
Image Grabber includes a preferences pane in the Settings application:
From the preferences pane, you will notice the first switch allows you to enable or disable the tweak on demand. Under this, you have the ability to choose whether Image Grabber will search your entire PDF file for images, or just the current page you are on – since Image Grabber has to process every image to use it, the current page is selected by default to increase speed. You can also select a minimum image size in terms of height and width to only include certain images in your Image Grabber interface. Below this you can adjust label fadeout, choose to have checkered (alpha) backgrounds, and adjust the viewer’s background white level.
Functionally, the tweak works exceptionally well and as advertised. Not only that, but the image extraction function is a practical function most iOS users could use. The interface even looks great, so we can't complain about it either way!
Image Grabber is an absolutely useful tweak, but not a necessity; it was created for the people that enjoy saving images all the time. Nikos explains that since this tweak is more of a utility than a customization tweak, it will likely only appeal to productivity users. Image Grabber was originally an experiment, however everything just went right with it. If you like saving images or e-mailing them easily, you should definitely take a look at Image Grabber and considering trying it out.
