A minor improvement to Dave Jarvis solution.

Instead of hard-coding the mime type in

images.put(id, "data:image/jpg;base64," + Base64.encodeBytes(data));

You can try to discover the mime type like this:

// Find out the mime type
final ByteArrayInputStream bis = new ByteArrayInputStream( data );
final String mimeType = URLConnection.guessContentTypeFromStream( bis );
// Convert to an embedded "data" url.
final String base64Data = "data:"+mimeType+";base64,"+Base64.encodeBytes( data );
imagesMap.put( id, base64Data );
