Standard Flash
The uppermost layer within the Flash banner should be the layer containing the transparent click through button. The action script which must be used with the ad's button layer is:
on (release) {
getURL("http://"_blank");
}
Important: do not copy and paste the above code into the Flash Actionscript window. The above is not raw text, so you'll get some special characters in with it which will cause the action script to look correct but not function.
Please note: The action script for the button layer in your Flash file should look exactly as it is above. Iinsert your URL where the "http:" is above.

Final Files Required: All advertisers wishing to use Flash creatives must supply the WDIG Advertising Account Manager with all of the following before the three day testing period can begin:
- Flash SWF (version 6 or less)
- Default GIF
- Click-through URLs
- Alternate Text
Flash CPU Usage Guidelines
Macromedia's Flash Player utilizes a computer's CPU (central processing unit) in handling all animation, masking, and computation contained within a Flash file. If a Flash file contains heavy amounts of mathematical computation for elements such as animation, loops, or timers, it will require a much greater percentage of CPU usage. As a result, the Flash file is forced to compete with other Flash files and other applications for CPU usage, which causes all Flash elements on the page to slow down significantly.
There are several ways to help cut down on the CPU usage your Flash file requires. One way is to limit the amount of "math-based" animation - animation which is controlled by mathematical-based action script. Another way is to limit or eliminate looping functions in action script. Looping functions are usually associated with timers. Masking and animated masking techniques can also require a large amount of CPU resources.
One way to estimate how CPU intensive your Flash file may be is to open the "Task Manager" (control+alt+delete) and view the "Performance" tab -- this gives a graphical estimate of CPU usage. With the Task Manager open, then open your swf file in the Flash player - you may see a spike as your Flash file is animating. A small spike of 20-30% is normal; if your CPU Usage jumps up to 80-100%, the Flash file may need revising until it uses less CPU resources.
For more information on optimizing Flash files, see Macromedia's article, "Streaming and file optimization techniques for Flash Player".
WDIG reserves the right to reject creative if it requires a higher than normal percentage of CPU resources and would, as a result of this, cause other page elements to slow down.
