The only way I know of to achieve this is to have the resizing happen in the page itself, not through the link.
Something like this should help:
Code:
window.resizeTo(intwidth,intheight)
The red items are the ones you would need to change. You could even do that dynamically through the link using query strings, if you really wanted to. You would just need to write your resizing script so that it grabs the width and height dimensions from the query string.
