The Flash banners created with our service follow the online ad industry standards. Some ad publishers may require the ad click-through URL (banner link) to be "hard-coded" (embedded) into the SWF file. Using the Pro service, you can hard-code the banner link in the SWF file. Alternatively, contact us with your order number and exact click-through URL, and we'll send you a copy of your banner with that URL embedded.
We also recommend to check with your ad publisher about the click-through URL browser window spec. By default, your Flash banner will open click-through URL in a new ("_blank") browser window - this is a typical requirement today. You can set your banner to open the click-through URL in the same ("_top") browser window through the interface of your Pro account.
