How to Add a PowerPoint File to a Blog

You can upload a PowerPoint to web then put a link in your blog for your visitors to download. They must have PowerPoint or PowerPoint viewer to view your presentation. If you want your PowerPoint to be viewed directly when visitors come to you blog, you should insert it as a flash file.

   • Create a new post or open edit an exciting one
   • Switch to Edit Html pane
   • Insert the flash to blog with the following html coding
     <object type="application/x-shockwave-flash"data=" URL of the uploaded flash file " height="300" width="400" align="middle">
     <param name="movie" value="URL of the uploaded flash file "/>
     <param name="allownetworking" value="internal" />
     <param name="allowScriptAccess" value="never" />
     <param name="enableJSURL" value="false" />
     <param name="enableHREF" value="false" />
     <param name="saveEmbedTags"value="true" />
     </object>
     Note:" URL of the uploaded flash file" included in the coding should be the URL of the uplaoded flash to web with the uploading services.
