How to resize images proportionally / keeping the aspect ratio?

Question

I have images that will be quite big in dimension and I want to shrink them down with jQuery while keeping the proportions constrained, i.e. the same aspect ratio.

Answer 1

actually i have just run into this problem and the solution I found was strangely simple and weird

$("#someimage").css({height:})

and miraculously the image is resized to the new height and conserving the same ratio!
