[Pharo-project] Sharing a image between several computers

Hi all, I've been programming in Smalltalk/Pharo for a time, and it is really nice (I love it). Usually, I work with several images at my work and home. I share those images using dropbox. However it is not practical, if your images size are 100+ MB (because dropbox is synchronizing each time that you save). So I was wondering If you use a more practical software to share your images between several computers. Greetings Oscar
