Change Image in gui

[sssssssssss]

If i have a script with imgctrl in it:

PHP Code:

    new GuiShowImgCtrl("Stan_Window_Image" @ this.guildflag) { 
      x = 12; 
      y = 50; 
      width = 150; 
      height = 150; 
      image = this.guildflag; 
    } 


And I need to change that image later, how would I go about it?

I tried doing a triggerserver on created, then get the image from dbnpc, then triggerclient, and set the this.gulidflag clientside, but that isnt working.
Also, on a whim, tried gui.setImage(this.guildflag), but I guess thats not a way to do it, kinda like setText.
