Hello,

I want to have an image on a master page which is changed depending on user. The problem is that there is often a pause on page change and the image can take a few mili-seconds to display as the script it executed. I would like it to be set at publication start or user login, only once so it doesn't occur on each page change.

Currently is flickers on each page change as the script it executed. Is there a method to set the image either via script or actions.
