InstaPix uses Internet-based peer-to-peer technology to let you share and exchange digital photos with friends and family. Create a gallery with one click and drag and drop photos into the gallery. Digital pictures are viewed in these galleries, where your invited guests can view your photos and add their own. Invite as many people as you like to join your galleries and post up to 36 pictures of any size. InstaPix instantly synchronizes all the photos within a gallery whenever a member logs in, automatically downloading any new photos to their machine. You can add comments to the gallery and chat live with InstaPix instant messaging.

Version 1.2.3 adds start-up performance enhancements and more image filters.
