If your not well versed with servers but want to run your own local web server, I recommend WAMP (windows apache mysql) very easy install, and has a mysql database to boot, suported by the latest php.
If thats too much of a hassle, or you change computers a lot, then drop box is the way to go.
It integratesw with windows, adding an extra folder in your my documents, which is a direct link to the online dropbox folder.
So placing something online is as easy as just copy and pasting it to another one of your windows folders :)
