How can i include an image created by GD on fly , to a php or phtml file?

<?php
header("Content-type: image/png");
$im = @imagecreate(110, 20)
    or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 0, 0, 0);
$text_color = i开发者_如何转开发magecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5,  "A Simple Text String", $text_color);
imagepng($im);
imagedestroy($im);
?>

How Can i include this image to my php or html file on fly by just putting an <img src="<? echo $im?>" />

Is it possible without saving the image and giving the path.

The only way I see would be to use data-URI, and to base64_encode() the content of your image into that ; which would get an <img> tag such as this one (quoting an example from the wikipedia page I linked to) :

<img src="data:image/png;base64,

But note it will not work with all browsers.

Helps to read the PHP Man pages, the comments provide some good information.
