Close Button: Please include a mandatory close button on 431x200 and 405x200, please make sure to add this command on the button: getURL("javascript:swfAction('close')");

Animation limitation: The playtime length of the animation should be between 10-12 seconds. The actions layer contains an action in the last frame on 431x200 and 405x200 getURL("javascript:swfAction('done')");

ClickTAG: All FLASH banners require a clickTAG. For ALL Flash banners a click TAG command on the button layer is required as shown below:

getURL("javascript:swfAction('click')");
}
The clickTAG button should be on the topmost layer.

IMPORTANT NOTES:

• The entire expanded area CAN be opaque, i.e. the ad can be in the form of an opaque rectangle covering the entire given space. Once the animation is played out, the ad will call the 431 X 83 gif and the 405 X 83 gif (for the narrow page).
• The animation of the ad has to be treated in such a way that both the ad units animate simultaneously and the users perceive it as one cohesive ad unit.
• Please check with the Yahoo! Sales Production team for further clarification.
• Please involve the Yahoo! Ad operations team in tweaking the animation of the ad.
