Twitter does not allow users to post pictures directly into their Tweets. Instead, Twitter users use image sharing services, including Twitpic, to post their photos. Then, the user posts a link to the picture on Twitter. If you have an Android phone or tablet, you can download the photos from Twitpic to your device.
Tap the link to the Twitpic image that you want to download.
Press on the image and hold your finger down until a menu appears.
Tap "Save Image" in the menu. The picture will download. You can find it in your Android device's "Downloads" folder.
