Grab URL as file upload for Drupal 7? When creating a content type, you have the option of adding a "file upload" field. How can I extend the functionality of this upload file to allow for the option of simply entering a URL instead of manually downloading the file and uploading it again? I basically want another field, called URL, where I enter the URL of the image. Drupal must then grab the URL as if though I uploaded it. Which means I must be able to "press upload" and actually see the thumbnail as per normal functionality.

I have a site from which we often grab images, but every time I first have to download it. It would save me a lot of trouble if I could just provide the URL and let Drupal do its thing.
You're looking for the FileField Sources module:


  FileField Sources is an extension to the FileField module. The FileField module lets you upload files from your computer through a CCK field. The FileField Sources module expands on this ability by allowing you to select new or existing files through additional means, including:
  
  
  Re-use files by an auto-complete textfield
  Attach server-side files uploaded via FTP
  Transfer files from a remote server (cURL required)
  Paste a file directly from the clipboard (Drupal 7 only)
  Select existing files through the IMCE file browser
  


Emphasis mine.
