Problem with save image file in src

Question

In image.php, the code likes:

header("Content-Type:image/png");
$file = "img.png";
readfile($file);

In other file, the code is:

<img src="image.php">

when I right-click from browser to Save Image As, it defaults to save as image.php. I would like to save it as img.png, any idea?

You could also just add this header to your PHP file:

header('Content-Disposition: attachment; filename="image.png"');

This could be accomplished through the use of URL rewriting.

In your .htaccess, add something like this (assuming mod_rewrite is enabled and you're on Apache):

RewriteRule ^image.png$ /image.php [L]

Your HTML changes with the file name to:

<img src="image.png" />

The image is generated by PHP file.

Correct. The URL rewrite maps 'image.png' to 'image.php'... image.php is getting called here.
