Question

I would like to have code for an image that counts the number of times the image is viewed, regardless of what site the image is found on. I want to use the img src tag, and have src point to a php page that counts that view and then returns the image to be viewed. I was thinking something like this:

 <img src="www.mywebsiteurl.com/something.php" /> 

How would I go about writing “something.php” so that it returns the proper image file? I know how to record the page view, but if I must do something different in this case, please tell me.

Answer 1

Your script needs to:

1. Record the hit.
2. Set the content type of the output ( header('Content-Type: image/jpeg'); )
3. Output the image ( readfile( $path_to_image ) );

For examples, please see the readfile documentation and Output an Image in PHP.
