You can use finfo  PHP 5 3   to get the right MIME type    filePath    YOUR FILE XYZ    finfo   finfo open FILEINFO MIME TYPE    contentType   finfo file  finfo   filePath   finfo close  finfo    header  Content-Type       contentType   readfile  filePath     PS  You don t have to specify Content-Length  Apache will do it for you

header  quot Content-type  image png quot     echo file get contents  quot     image png quot     The first step is retrieve the image from a particular location and then store it on to a variable for that purpose we use the function file get contents   with the destination as the parameter  Next we set the content type of the output page as image type using the header file  Finally we print the retrieved file using echo

You can use header to send the right Content-type    header  Content-Type       type     And readfile to output the content of the image    readfile  file      And maybe  probably not necessary  but  just in case  you ll have to send the Content-Length header too    header  Content-Length      filesize  file       Note   make sure you don t output anything else than your image data  no white space  for instance   or it will no longer be a valid image

For the next guy or gal hitting this problem  here s what worked for me   ob start    header  Content-Type     mimetype   ob end clean     fp   fopen  fullyQualifiedFilepath   rb    fpassthru  fp   exit    You need all of that  and only that  If your mimetype varies  have a look at PHP s mime content type  filepath

Expanding on the accepted answer        I needed to      log views of a jpg image and an animated gif  and    ensure that the images are never cached  so every view is logged   and    also retain the original file extensions        I accomplished this by creating a  secondary   htaccess file in the sub-folder where the images are located  The file contains only one line     AddHandler application x-httpd-lsphp  jpg  jpeg  gif   In the same folder  I placed the two  original  image files  we ll call them orig jpg and orig gif   as well as two variations of the  simplified  script below  saved as myimage jpg and myimage gif       lt  php    error reporting 0     hide errors  displaying one would break the image       get user IP and the pseudo-image s URL   if isset   SERVER  REMOTE ADDR       ip    SERVER  REMOTE ADDR    else  ip    unknown       if isset   SERVER  REQUEST URI       url   SERVER  REQUEST URI    else  url   unknown          log the visit   require once  connect php                 file with db connection info    conn   new mysqli  servername   username   password   dbname     if    conn- gt connect error              if connected then save mySQL record     conn- gt query  INSERT INTO imageclicks  image  ip  VALUES    url     ip             conn- gt close        datetime is auto-added to table with default of  now             display the image    imgfile  orig jpg                                  or  orig gif    header  Content-Type  image jpeg                    or  image gif    header  Content-Length    filesize  imgfile      header  Cache-Control  no-cache      readfile  imgfile     gt    The images render  or animate  normally and can be called in any of the normal ways for images  like an  lt img gt  tag   and will save a record of the visiting IP  while invisible to the user

If you have the liberty to configure your webserver yourself  tools like mod xsendfile  for Apache  are considerably better than reading and printing the file in PHP  Your PHP code would look like this   header  Content-type   type    header  X-Sendfile   file      make sure  file is the full path  not relative exit      mod xsendfile picks up the X-Sendfile header and sends the file to the browser itself  This can make a real difference in performance  especially for big files  Most of the proposed solutions read the whole file into memory and then print it out  That s OK for a 20kbyte image file  but if you have a 200 MByte TIFF file  you re bound to get problems
