Why showing images through PHP might be useful:

  • Being able to control/restrict access to the images in a complex way (e.g. not just by http auth, ip, referer etc.).
  • Being able to dynamically modify images before they are displayed (watermarks for example)

How you do that:

Send the appropriate header for whatver image type (e.g. header('image/png');) you want to show and then output the raw image data, e.g. using readfile()
