Resize Image To Window Height When Called From Link?

Can I get Images to resize to window height when called from an 'a' link created in a cell of 'insertRow'.

Something like this
Code:
var additemlink=top.frames['register'].document.createElement('a');
additemlink.setAttribute('id','itemlink'+count);
additemlink.setAttribute('href','zanfeld/p'+code+'.jpg');
additemlink.setAttribute('target','display');
additemlink.setAttribute('title','Review this item then click your back button to return');
additemlink.className='itemlink';
additemlink.appendChild(document.createTextNode(item));
additemlink.onclick=function(){resize(this, 100, 100);};
additem.appendChild(additemlink);

I've seen a lot of inline scripting for this but no dynamic unobtrusive 'resize' image examples are to be found.
