Create Image in Image Plane; Mel Command

[mayameler]

First off I love the site and it has been very helpful.
Im trying to create a script where the script will take an predetermined image and create an imagePlane. From reading over previous posts I have found code to make the plane:
createNode "imagePlane";
connectAttr imagePlane1.message cameraName.imagePlane;

But have not found any info on attaching a specific file. I've been searching around for an answer on this for a while. Any idea? Lets say the image location is represented by the variable $imageLocation. Many thanks for any help.

setAttr -type "string" imagePlane1.imageName "pathunderprojectfile.ext";

or

setAttr -type "string" imagePlane1.imageName "drive:pathpathfile.ext";

as expected, it works like a charm, thanks a lot!
