You don't have your facebook photo on your computer hard drive? You can just download it from your profile I guess, if you don't and then upload it on that other website.

If you only want a soft for your music and video files then I can recommend you Audials. I am also using it with my cloud storage accounts, besides other things. And I think you could find it very useful especially that you can record online streaming music and videos with it, convert the files and then transfer them to your Dropbox cloud storage. You can also import files from the Dropbox cloud to your computer and even play the music and video files that are on the cloud. It's pretty convenient actually. You can have a look here, there is a tutorial on how you can use it with a Dropbox account: http://audials.com/en/cloud/dropbox.html. Wll hope this helps!
