On some sites, you can press and hold the picture on the screen until the Save Image command appears. In the Safari browser, the tool bar’s Share menu also has a Save Image option. By default, the downloaded image files land in the Camera Roll album in the Photos app. Just look for an Insert menu or a photo icon in the app’s tool bar. Tap the icon, select the downloaded art file from the Camera Roll and add the image to your document.
