Q425 How can I read client-side files or upload them to a server?
Mostly true, but unlike Java, it's possible to use files on client machine.
For example use HTML file upload form element to browse for file on client. The file name is then submitted as query string to a web page, the file name can be document.written to incorporate it into the web page.
I use this to incorporate an image on the client machine into a web page (see below). It's purely client side.
