There might be a mistake in here. Sorry to burst the bubble, but I hope you can figure it out, because I think resizing is such a neat trick, and I will be using it in the future. So thanks. But...
When you do the resizing to 350x0, the picture shows in a different size, as when you resize AND do the pull-right. Even though both should be 350x0 as to your explanation. So it seems, the resizing is overruled by the pull-right command.
