Or search 'G Space'

G Space; Firefox Addon

It turns your gmail account into a virtual drive.

Gmail currently has over 5 gigs of space (and counting) that most people can't fill with regular email. You can have multiple gmail accounts set up through this, so I have one for pictures, one for music.

This works well because you can play music that you have uploaded to your gmail account through G Space! You can view individual pictures as well.
