Few days ago, I was worked on design of my site, I wanted to include flash slide show into it, I added flash normally. my work was perfect, everything worked fine, but W3C has founded some error in my site, this errors were because of flash <embed> element, later I have read this blog http://alistapart.com/articles/flashsatay, here is written about, one of the most used and popular technique, how to add flash movie in your content with W3C specification.
This technique is simple, <embed> element was created by Netscape, it’s not part of the XHTML specification and because of that W3C has found there errors. We can remove <embed> element and all will be ok there will be no errors, but movie will be displayed only in IE, not in Mozilla or Netscape what to do ? here is example

If we want to include flash movie with name slide.swf normally we will add this code in our page

<object
classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com
/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0"
width="400" height="300" id="movie" align="">
<param name="movie" value="http://Full Location URL/slide.swf">
<embed src="http://Full Location URL/slide.swf" quality="high" width="400"
height="300" name="movie" align=""
type="application/x-shockwave-flash"
plug inspage="http://www.macromedia.com/go/getflashplayer">
</object>

that was normal flash displaying method, which used by many web masters.
This is W3C friendly method, we have deleted <embed> and added some optimized parameters, look at the code

<object type="application/x-shockwave-flash
data="http://Full Location URL/slide.swf?path=movie.swf?path=movie.swf"
width="400" height="300">
<param name="movie"
value="http://Full Location URL/slide.swf?path=movie.swf?path=movie.swf" />
<img src="noflash.gif"
width="200" height="100" alt="" />
</object>

How you see we have not used <embed> any more, we displayed flash movie, with this “http://Full Location URL/slide.swf?path=movie.swf” parameter which we added in <object> and <param>. Thats all, I think that was simple, if you want full information you can found it at that blog http://alistapart.com/articles/flashsatay. You can use this technique when you want to display flash movie at you page.:)
