title: Allow users to upload image in shopify
body: <p>Is there any way i can allow users to upload images to a contest page in shopify users. I have searched a lot but no luck with shopify discussion forum or any thread. 
  Basically, I Want to allow users to upload images and those images need to be appear(after admin approval) in contest page for voting. Users can also vote for the best images available in Contest page.</p>
  
  <p>Is there any app or do i need to do it manually?</p>
