Align content to top of image marker

[JamesBotterill]

I'm attempting to to aligning content to the top of the image marker using the arjs-nft-init-data and then using (msg.width / msg.dpi * 2.54 * 10)/2.0 to align to the middle of the marker, but on the y axis I'm stuck trying to position to the top of the image.

Any help would be awesome
