How to detect browser no flash give alternate with gif

Let see, we have one file .swf and one file .gif and we want display the flash file first, and if the browser doesn't support, it will display the .gif version.
Here is the code.

JAVASCRIPT CODE:
<br /><object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://active.macromedia.com/flash/cabs/swflash.cab#version=3,0,0,11" name="sw" id="sw" height="164" width="165"><br /><param name="movie" value="file.swf"><br /><param name="quality" value="high"><br /><param name="Loop" value="true"><br /><param name="play" value="true"><br /><param name="wmode" value="opaque"><br /><param name="allowScriptAccess" value="sameDomain"><br /><param name="bgcolor" value="#000000"><br /><br /><!-- begin the JavaScript --><br /><script language="JavaScript"><br /><br />//If this browser understands the mimeTypes property and recognizes the MIME Type //"application/x-shockwave-flash"...<br />if (navigator.mimeTypes && navigator.mimeTypes["application/x-shockwave-flash"]){<br /><br /> //...write out the following <EMBED> tag into the document.<br /> document.write('<embed src="file.swf" quality="high" bgcolor="#000000" width="165" height="164" name="pmi_flash" align="middle" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" LOOP="true" PLAY="true" wmode="opaque" />');<br />}<br /><br />//Otherwise,...<br />else {<br /><br /> //...write out the following <IMG> tag into the document. The image need<br /> //not be the same size as the Flash Player movie, but it may help you lay out the<br /> //page if you can predict the size of the object reliably.<br /> document.write('<IMG SRC="file.gif" >');<br />}<br /><br /><br /></script><embed src="file.swf" quality="high" bgcolor="#000000" name="pmi_flash" allowscriptaccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" loop="true" play="true" wmode="opaque" align="middle" height="164" width="165"><br /><br /><!-- Close the OBJECT tag. --> <br /></object><br />

My Editor Wysiwyg ?

I choose for WYSIWYG Editor for web, the best and free is:
http://xinha.python-hosting.com

Here is some description from the web:

Xinha (pronounced like Xena, the Warrior Princess) is a powerful WYSIWYG HTML editor component that works in Mozilla based browsers as well as in MS Internet Explorer. Its configurabilty and extensibility make it easy to build just the right editor for multiple purposes, from a restricted mini-editor for one database field to a full-fledged website editor. Its liberal licence makes it an ideal candidate for integration into any kind of project.

Xinha is Open Source, and we take this seriously. There is no company that owns the source but a community of professionals who just want Xinha to be the best tool for their work.
