There are many online image sharing services available including the popular ones like Flickr, Instagram, Picasa, Facebook, 500px, Photobucket etc. But these services does not have any option to transfer photos from one online service to another one. Pi.pe is an online free service which allows you to move your media files including photos and videos to another online service. The web app supports most of the popular services like 500px, Facebook, Flickr, Instagram, Kodak Gallery, MySpace, Photobucket, Shutterfly, Smugmug etc.
The service has a wizard like interface where you first select the source for your media files. You will be asked to login and grant permission for the app to use your media files.
In the second step, you select the albums (or photos) which you want to move to other online service. It lists out all the albums available.
The final step, you select the service to which you want to move the photos. Here you have a wide range of services including Dropbox, Box.net, YouTube, Google Drive, Orkut, Evernote, YouTube (for videos) etc.
The app will verify your account and check if there is enough space on the account your have selected to move the media files to.
Pi.pe is definitely a good service if you want to to move large number of media files from one service to another.
Currently the service is invite only, but you can use the invite code “getpipe” at http://pi.pe.
