Over the past couple days at least 3 others have asked me how to embed a valid flash file in their Ning network. So here is a tip. Are you often embedding Flash files into your html pages? If yes, you’ll better save the valid flash embed code below for future use.
<param name="movie" value="your-flash-file.swf" />
<param name="quality" value="high"/>
Simply upload your flash file through a text box or your file manager and replace the parts in red with your file URL.
Hope this helps guys and gals. Let me know if you need help.
