Adding A Flash Movie To Your Website: To incorporate a Flash Player (.SWF) file into your website, just use the following HTML code: In both instances, "Filename.swf" is the actual filename of the SWF file, and you'll want to set the WIDTH and HEIGHT parameters (which are shown as x in both instances here). If you want to make the background color something other than white, change that too (here it's set to FFFFFF, which is white).
