I would like the height*width of a remote image. Could that be done with Curl, and if so how?

See Question&Answers more detail:osgetimagesize() is the function you want.
It should be able to download a remote image and analyze it.
Edit: As a more direct answer to your question, Curl cannot analyze an image directly, but it can certainly fetch it for you, in which case you can then use the GD library to analyze it. getimagesize() manages to do the fetching as well though, so you can leave Curl out of the equation.
