Macromedia Flash Banner Specs

For advertisement to display and click through properly on our websites, the following instructions need to be followed exactly when constructing a .SWF banner in Flash. *.SWF banners are accepted only for the 728×90, 468×60, 300×250, and 300×600 banner zones on,, and Flash ads can only have user-initiated audio. Video files must pause after 15 seconds but can be re-initiated by the user for an unlimited amount of time. Our most current version of Flash is 8.0.

  • Open your Flash file (.FLA).
  • Lock all layers.
  • If you have not already done so, create a new layer at the top of the layer stack and name it “actions” (without quotes).
  • Create a new layer at the bottom of the layer stack.
  • Name it “btn” (without quotes).

  • Select the first keyframe on the “btn” layer.
  • Draw a rectangle the size of the stage with no stroke and a fill of the same color as the movie’s background color.
  • Double-click the new rectangle to select the entire rectangle.
  • In the Align panel, with “Align/Distribute to stage” selected:
    • Click Align horizontal center
    • Click Vertical horizontal center
  • The rectangle should be covering the entire stage.
  • Convert your selection to a movieclip (F8) and type “btnMC” in the name field.
  • Make sure that its Type is set to “Movie clip” and its Orientation Point is set to upper left.

  • Select the instance on the stage.
  • In the Properties panel, give it an instance name of “btn_mc” (without quotes).
  • Lock the layer.

  • Select the first keyframe in the “actions” layer
  • Open the Actions panel and type the following:

btn_mc.onRelease = function() {
getURL(url, window=”_blank”);

  • Please note that the URL is picked up from our ad server and shouldn’t be in the FLA coding
  • Note: Under File -> Publish Settings -> Flash, be sure to publish as ActionScript Version as “ActionScript 2.0.” Unfortunately, ActionScript 3.0 will not function with our system.
  • Save and publish your movie

Please submit both the .FLA (zipped with fonts) and .SWF file along with a landing URL to [email protected]. We perform QC testing on .SWF banners before uploading to our websites and will alert you to any coding that does not comply with our requirements.  Please note that we can only accept .SWF for larger zones on and
