A free program for Android, by Fog Creek Software.
Media Organizer is an Android app that is integrated with Gallery, Gallery3D, and HTC Sense Album and lets you manage all of your photos, pictures, and videos in one place.
It allows you to create and organize albums and folders, import photos and videos from your external storage (SD card), create and manage multiple albums at the same time, and even view photos and videos by using the built-in media player.
You can also use the built-in image, video, and music editor to edit your photos, change the album art, add text, and apply other effects.
Media Organizer can also be used as a standalone app and works with any gallery app.
