I have a DOM with an image, image height, image width, link ID assigned by a SimpleTreeDropdownField, and a link name which is just a friendly view of what page the link ID is for.
I'm using an onBeforeWrite to grab the height and width of the image as well as the link name from the link ID. In this scenario if somebody uploads a replacement image with the same name and different dimensions, or changes the Page Name of a page that is linked, the info in the DOM will be incorrect. What is the best way for me to keep the DOM info accurate?
Also, is there any way to include a null option in the SimpleTreeDropdownField in the case that I would not want to include a link on a particular object?

Yeah, it works just like a DropdownField..
$dropdown = new SimpleTreeDropdownField(...);
