One of the great features of the Android browser (and most third-party browsers) is the ability to save any picture you might find on websites. You simply long-press on the image, and a menu pops up. Sometimes you may get several more options if the picture links to another webpage.
Once you save the image, you can quickly find it within your "All downloads" album in your gallery app, or just click on the file once it finishes downloading. As an example, this is a great way to find and use wallpapers for your Android phone. Enjoy!
