here's some more detail on my earlier post, hopefully it can provide better direction. trust me, this works

Embedding showit web into your blog (Internet Explorer friendly version)
Step 1:
http://blog.deconcept.com/swfobject/#download Download swfobject, unzip and upload swfobject.js and upload it into your blogs main directory (
http://www.yourserver.com/blog/swfobject.js)Step 2: Go into wordpress, write a post, click on CODE and paste this in
<script type="text/javascript" src="swfobject.js"></script>
<p id="flashcontent">type in text here so google knows the content</p>
<script type="text/javascript"> var so = new SWFObject("http://www.yourserver.com/slideshows/slideshowname/showit.swf", "showit_swf", "600", "400", "8", "#000000"); so.addParam("quality", "best"); so.addParam("wmode", "transparent"); so.addParam("salign", "lt"); so.addParam("loop", "false"); so.addParam("flashvars", "showit_embed= "http://www.yourserver.com/slideshows/slideshowname/|600|400|1|0|0");" so.write("flashcontent");</script>
Step 3: This is where we take my code and customize it for your specific slideshow. Where it says "showit_swf", "600", "400", "8", "#000000"); Make sure you replace 600 and 400 with the width and height of your slideshow (I made mine 600px by 400px in this example) #000000 is what the background color of the show is, mine is black, but you can make it white by typing #ffffff or using photoshop to find whatever other color you want
Replace the 600 and 400 accordingly where it says "showit_embed=
http://www.yourserver.com/slideshows/slide...0");" again, it's the width and height of the show
Replace
http://www.yourserver.com/slideshows/slideshowname with whatever directory you place your slideshows
If you type in the width and height of your shows, along with the directory where your slideshow is, I can generate the specific code for your situation. The key though is getting that swfobject.js file into your blog's main directory.
Best of luck all!
