Image Downloader

Allows you to download images from remote images in a cost effective way. Before downloading an image it makes a HEAD request and checks the Content-Type, and Content-Length headers in HTTP Response.

If server reports an image is at that URL, Image Downloader will issue a GET request and download the image.

image-downloader's Issues

Make ImageDownloader to download images

It should be able to download images:

  • check image size (via Content-Length), and Content-Type before actual download with HEAD request
  • download image and save to file system
  • verify file is valid image using getimagesize

Errors

Appropriate Exception should be thrown if an error occurs.

Content-Length check

Script must not rely that Content-Length and Content-Type headers are going to be present, since many server administrators have HEAD HTTP requests disabled.

Content-Type check

Content-Type check is complicated because there are way too many MIME types for images. Therefore, create a separate ImageDataTypes class holding a list of valid MIME types.
