title: Do you think it's a good idea to save billions of images into Database?
body: <p>Recently, I and my colleagues, we are discussing how to build a huge storage systems which could store billions a pictures which could searched and download quickly.</p>
  
  <p>Something like a fickr, but not for an online gallery.  Which means, most of these picture will never be download.</p>
  
  <p>My colleages suggest that we should save all these files in database directly.  I really feels that it's not a good idea and I think database is not desgined for restore huge number of binary files.  But I have very strong reason for why that's not a good ideas.</p>
  
  <p>What do you think about it.</p>
