I’ve tried:

var fn:String = "image.png";
var f:File = File.applicationStorageDirectory.resolvePath(fn);
var subject:String = "My encrypted Image";
var body:String = "<html><head><body><img src=\""+f.url+"\"></body></head></html>";
var url:String = "mailto:?subject="+subject+"&body=" + body;
navigateToURL( new URLRequest( url ), '_self' );

This does launch the Mail app but it displays a “?” icon, which means it can’t find my full app-storage path.

Any ideas?

Thanks

    I found a solution:

    instead of putting the file path, put a Base64 encoded string of the image, for example:

    <img src=\"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==\" alt=\"Red dot\" />
