Change Image in gui

[sssssssssss]

Ill post the code its using in pieces. I tried some of those, they didnt work.
The gui weapon:

PHP Code:

function onCreated() {
  this.db = findnpc("db_registeredguilds");
}

function onActionServerSide(action, acton) {
  if (temp.action == "getImage"){
    triggerclient("weapon", this.name, "getFlag", this.db.getGuildFlag());
  }
}
//#CLIENTSIDE
function onActionClientSide(cmd, data, data2) {
  if (cmd == "getFlag"){
    Stan_Window_Image_.image = temp.data;  
    this.guildflag = temp.data;
    player.chat = temp.data;
  }
}
function onCreated(){
  triggerserver("weapon", this.name, "getImage");
}
new GuiWindowCtrl("Stan_Window") {
    profile = "GuiBlueWindowProfile";
    useOwnProfile = true; 
    extent = "495 300";
    x = 50;
    y = 50;
    text = "Guild Registration Lobby";
    visible = true;
    canResize = false;
    new GuiShowImgCtrl("Stan_Window_Image") { 
      x = 12; 
      y = 50; 
      width = 150; 
      height = 150; 
      image = ""; 
    } 
} 


PHP Code:

DBNPC
public function getGuildFlag() {
  return this.guilds.(@player.guild).flag;
} 


the flag is

PHP Code:

guilds.guildname.flag="block.png" 


also tried the flag w/o quotes.

in the set for the image on the action clientside ive tried:
setImage,
setImg,
and using a variable then putting the variable in the gui image = section.
With the code that is posted, all that shows up is a big "0" (zero) when I use

PHP Code:

this.guildflag 


if i use it blank as shown, it shows up nothing.
i put player.chat and its saying "block.png" when i use so I know it shouldnt be empty, its just not setting.

If im doing this completely wrong, can someone show an example and please explain how it works? really wish graal.net worked. :/
