Output an Image in PHP

Question

I have an image $file ( eg ../image.jpg )

which has a mime type $type

How can I output it to the browser?

Answer 1

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.
