1. Banner summary

It is recommended to use Poster code if a banner should be displayed only after a user scrolls to its placement. On this code banner is displayed after complete loading of the webpage. In other cases it is strongly recommended to use Extension code.

2. Flash-movie preparation

You should prepare two flash-movies: the big one and the small one. For the small flash-movie you should also prepare a .gif or .jpeg image, which will be shown to those users who do not have a compatible version of flash player installed. Width and height of the image and the small flash-movie must be the same.

The first frame of flash-movie should contain the following ActionScript:

if(ar_init == undefined){
 ar_init = true;
 System.security.allowDomain('*');
}

System.security.allowDomain(‘*’) allows the downloader to access banner variables and properly initialize click variable link1. It is not necessary to specially permit access in a downloader to those movies which are being downloaded.

Your flash movie should contain a button element with the following ActionScript:

on (release) {
       getURL(_root.link1, "_blank");
}

You should obligatorily use the link1 variable, it is used for counting clicks.

If it is necessary to open a banner link in a current window you can use the value _top of a target variable.

on (release) {
       getURL(_root.link1, "_top");
}

If you client is using AdRiver as a main system for online-advertising management on his site you can use the following code:

on (release) {
       getURL(_root.link1, _root.target);
}

This code allows to open banner link either in a current window or in a new window according to the option that was choosen in AdRiver interface.

For the button element that expands the banner by the user’s click on it write the code given below:

on(release){
   flash.external.ExternalInterface.call("window.showSG");
}

In big flash movie you should also create the button which makes the banner reduced. Write the following code for the button:

on(release){
   flash.external.ExternalInterface.call("window.hideSG");
}

3. Script preperation for banners on Poster code

Download an example. Open a script.js file with a text editor. You should change only that part of code, which is marked as “Editable block”.

var gifname			= '0.gif';
var giflocation			= '';
var smallflashname		= 'bannerSmall.swf';
var smallflashlocation		= '';
var ar_height_small 	 	= '90';
var ar_width_small	 	= '704';
var bigflashname	 	= 'bannerBig.swf';
var bigflashlocation	 	= '';
var ar_width_big	 	= '704';
var ar_height_big	 	= '180';
var ar_valign	 	 	= '1';
var ar_align	 	 	= '1';
var ar_flashver	 	 	= '9';
var ar_alt_link	 	 	= '';
var ar_zeropixel	 	= '';
