The Gallery app presents all of the pictures and videos stored in your phone, including those you’ve taken with the Camera app, those you downloaded from the web or other locations, and on your microSD card (if inserted and mounted). When another app saves a picture, it automatically creates an album to contain the picture (e.g., capturing a screen shot creates the Screenshots album).
