File Sharing Sites?

I'm currently trying to find a file sharing site where I can put some of my papers and pictures that I want to link up here at Blogger. Currently I'm going through Angelfire.com, where I have my old blog and website, but they do not allow me to directly link to papers or pictures. At the moment, given the changes in location and beginning graduate school in August, I cannot afford a payed service. Does anyone know of any free file sharing sites that I can look into?
