I noticed PhotoResizer wouldn't take RAW in any form. I suppose it would totally defeat the purpose if it did.
I'm not sure what my Yahoo e's limit is. But I'd just wondered how one did it, without a real need to do it right now. But later it would be nice to be able to host, send and receive for the new screen size of 1920 X 1080. No rush.
I usually aim for about 200k. for pprune. They seem to fit quite well. Too big and I take away the IMGs. Then it (the link) just fits! I have no idea how.
