I understand Gears allows local storage of remotely sourced web data. I don't know of any way it solves the problem of embedding PNG in a locally saved html file so the file can be viewed on a machine which doesn't have my server installed, and which may not be connected to the network at the time.
This is a note taking application at first, with the idea of making the notes 'smarter' in later versions. I'd like to have the notes always viewable just with a browser, just as with any locally saved html file. The notes would be read-only, and not smart, but accessible. So my question is more how to embed (PNG) data presented with a GWT Image widget into a saved html file so it can be displayed in a 'dumb' browser. The Image is how the handwriting is shown, with backing smarts in the full application. Thanks.
