Notes

Yahoo! does not allow 3rd party serving of HTML/JavaScript code. Approved Yahoo! 3rd Party Servers are only authorized to serve the alternate images and/or the click-thru urls.
Client-side imagemaps are acceptable and must be provided by the client.
Forms tags in the HTML code must use 'get' in the method.
CGIs referenced in the HTML code must be active at the time of ad submission for validating/testing the ad HTML code, and able to handle the traffic load. Ads with CGIs which are not active and/or cannot handle the projected traffic will not be accepted.
No CSS stylesheets are allowed - any styles used should embedded directly in the tags of your HTML.
If you require javascript functionality please see the Javascript/DHTML guidelines
