It’s easy to save images you find online to your Apple iPad, iPhone or iPod touch with iOS 5.0 or higher. Here’s how to save images via Mobile Safari to your mobile Apple iOS device.
Find the page with the image you want to save. Long-press the image until you see the menu below. Tap Save Image.
That’s it. Now open Photos and you’ll find the image you just saved. It will be the last picture on your list. Tap on it to get a larger view.
Then tap Options to email the image, assign it to a contact, tweet or print it.
The process works the same on the Apple iPhone and iPod touch. The menus are just different.
