I have a web application with a Dojo Rich Text Editor. Within the editor, if I paste an image from an external url such as http://www.google.com/intl/en_ALL/images/logo.gif, the image shows up fine in the editor.

However, if I paste an image from my hard drive, then that image does not show up. My guess is this happens because the web application is deployed to a server and the image cannot be accessed from the server. Is that true? If so, is there an alternative? Is it possible that I can detect the paste event on the editor, determine what is being pasted...and then in the background upload that image to the server somehow so that it can be accessed by the web app?

I'll appreciate some direction on this issue.
