Z-Layering Images In Report

[dMac314]

Hello out there!

I am trying to place a "Clear-All" button (Image) in one of my reports but do not want to resize anything. 

I would like to place this button in the top corner "Above" a graph, in the white space, but when I implement the book mark logic I can't click the button because it always ends up below the chart. How do I assign precedence to these images? Is there a way to assign a z-value to these "Layered" images so they will be at the fore front of the report?

Thanks!!
