Is it legitimate to use dropbox as file storage for my site?

Question

I am approaching the limits of my hosting plan. I doubled it once from 2 to 4 GB and my site (a popular woodworking community in Hebrew) is getting close to using the disk space

Answer 1

Look in to Rackspace Cloud Files and Amazon S3. You can hotlink directly to the files.

Alteratively, have your users use an image hosting service like Flickr or photobucket, and have them provide links instead.
