title: How to show percentage of upload in progress bar?
body: <p>I'm using Paperclip for image upload. I need to show percentage of size uploading to server in the percentage bar. Can anyone please offer me a solution that could be compatible with paperclip. (If Uploadify would be the solution, can you please suggest a tutorial for how to use it along with paperclip)</p>
  
  <p>P.S. Sorry, Of course, there are many similar questions around forums, but I couldn't find an appropriate solution for my need and more'er, most of them leads to an outdated solution or landing in a "not found". So, any help would matter a lot. TIA! </p>
