Bill, This is very interesting to me. I have wanted to think about the broader design of a successor to image3 and using system resources and the built in bmp utilities makes sense (these were not available way back then). But there are impediments and image3 has been so darn stable. I would love to see some typical examples of how you integrate your use of platimg and image3 and if you can articulate why this has been effective for you I would be most interested. Thanks for your remark in any case -- it is very thought provoking. Best, Cliff
