How to resize watermark to be the same size for vertical/horizontal images?

Question

I am using File -> Place menu to place my watermark onto the images. 
No matter what I try so far, the absolute size of the watermark comes out different Portrait/Landscape images.
Watermark is smaller on Portrait and larger on Landscape images.  I tried resizing writing in the number of pixels during the File->place command, but no luck.  Photoshop resizes the watermark based on the percentages, and I don't know why image orientation matters. 
ideally I want my watermark to be the same size, and I can use absolute pixel dimensions if needed.  How do I do this?

Hi Doug - What exactly are you trying to do? Is the third
child being added dynamically, and you want it added above the
first child? If so, you can use the addChildAt() method when adding
the child to the container. addChildAt() takes an index and the
child object is added at that index and all other children are
reshuffled to maintain the ordering. IE:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="vertical">
<mx:TitleWindow layout="vertical" id="tw">
<mx:Button id="a" />
<mx:Button id="b" click="go();"/>
</mx:TitleWindow>
<mx:Script>
<![CDATA[
private function go():void
var c:Button = new Button();
c.label="new";
tw.addChildAt(c, 0);
]]>
</mx:Script>
</mx:Application>
Does that help, or am I misinterpreting what you're trying to
do?
