Here goes:

1. Sign up for a Blogger blog and a Dropbox account. (Here’s a link for the latter.)
2. Copy your multimedia files (.mp3, .swf, etc.) to the Dropbox public folder.
3. Go to the Dropbox Web interface and click into your Public folder.
4. Use the arrow to get the public URL for the file in question.
5. If you’re trying to embed audio, copy this text into your Blogger entry:
   <embed src= “http://www.odeo.com/flash/audio_player_standard_gray.swf” quality=”high” width=”300″ height=”52″ allowScriptAccess=”always” wmode=”transparent” type=”application/x-shockwave-flash” flashvars= “valid_sample_rate=true&external_url=[MP3 URL HERE]” pluginspage=”http://www.macromedia.com/go/getflashplayer”> </embed>
6. Replace [MP3 URL HERE] with the URL  you copied from Dropbox.
7. Publish.
8. For SWFs, do the same as above, but use this embed code:
   <embed src=”[SWF URL HERE]” quality=”high” allowscriptaccess=”always” type=”application/x-shockwave-flash” pluginspage=”http://www.macromedia.com/go/getflashplayer” align=”middle” height=”[###]” width=”[###]“></embed>
9. In this instance, replace [SWF URL HERE] with the Dropbox public URL and [###] with the appropriate SWF sizes.
10. Publish.

That’s it.
