title: rails paperclip default image with S3
body: <p>I'm trying to use the default_url in my application but I store the images using S3. I'm not sure what URL I need to put in there or if I have to create a fake image just to get everything up there.</p>
  
  <p>Since my images always render through S3, I don't know if it would work if I just put in some default images in my public folder. It doesn't seem to be working now - I also only have one image in there, and I know it has to resize. I can manually put the resized images in there but I'm still not sure what URL to use with default. Please help :)</p>
