Question

I really do not know any PHP but I’d love to do one simple thing:
I access a php page from within a <img src="/myhumbleimage.php" /> and I’d like to have an image returned from another URL.

---

I came up with:

<?php
header('Content-Type: image/png');
readfile('i' . rand(1,3) . '.png');
exit;

And it works:
Avatar selection http://vercas.webuda.com/img.php?.png
(Reload the page a few times!)

Answer 1

Check out readfile().

The basic idea is you send the appropriate MIME type headers (using header()) then deliver the file contents using readfile().

For example

<?php
// myhumbleimage.php

// Do whatever myhumbleimage.php does before the image is delivered

header('Content-Type: image/jpeg');
readfile('path/or/url/of/image/file.jpg');
exit;
