Instagallery for iPad lets you view and interact with Instagram photos, create slideshows
Instagallery is an iPad app that lets you view a gallery of Instagram photos. The app shows you popular Instagram photos once you start it up, but you can also sign in with your Instagram account. If you do that, you'll be able to see photos from the people you follow, view your own photos, "like" photos, view and add comments, and see who your friends are following.
Photos are shown at full size on a neutral background. While you're viewing a photo you can easily jump to more photos by the same user, other pics from the same location, or more images with a specific tag. You can also find photos with tags that match your interests, as well as search for people you know and follow them.
Instagallery also lets you view any set of photos as a slideshow. You can adjust the display time for each photo, and set the slideshow to auto-repeat.
