Using the local webserver
If you use Mac OSX, then you’re machine is also a webserver – you just need to know how to deal with it. Turn it on in the Sharing preference panel, then look in /Library/WebServer/Documents – that’s where your “root” directory is. Put images, notes to yourself, whatever you want in there, and it’s accessable from your web browser – either go to http://localhost or http://127.0.0.1 to view it. If you’re on a network (i.e. you have multiple computers at home, or you’re in an office), then other folks can access your computer (via Apples Rendezvous or by your IP address) – so be careful what you put there!
