animate the size of an image

animate the size of an image

hi folks!

im searching for a short explenation for handling image animation regarding this situation:

  1. $('img).animate({
  2.       width: "106px",
  3.       height: "153px"
  4. }, 1500 );
when i use this code the image is blowing up from the left top corner to the size i declared in the animate function. but im searching for a animation out of the middle of the current size to the declared one.
so it shoulndt blow up from top left ..more it should blow up to all corners at same time.

can someone show me an example or something like that?

greetings
stefan

P.S. Im sorry for my bad english!
