Dropbox is a handy place to store images, kind of like an external hard drive. You can set up images in a way that gies them a public link so they can be displayed on message boards and in emails.
Wikipedia says - Dropbox is a Web-based file hosting service that uses cloud computing to enable users to store and share files and folders with others across the Internet using file synchronization.
An account at Dropbox allows you to display images easily and sync your files online and across your computers automatically. You can do a lot of other cool things there and it is easy to set up. Here is a link, (note: with my referral number in it) for signing up for a free account.
