Possible Duplicates:
Want to render an image without saving it to disk using PHP GD libs
The image cannot be displayed because it contains errors.
I'd like to call a function that make a image trought the img src tag. Is it possible?
I mean : instead of call <img src="path/file.php" /> I'd like to do somethings like <img src="function()" />
PHP is server side; It can generate either a base64_encoded image result which can be placed as an image, or you can point to a php script that will generate an image. But, regarding client side, it won't work.
So, you could do the following:
// the browser will make a call to your generator to render an image back
echo '<img src="myimagegenerator.php" />';
// src will be something like "data:image/png;base64,..."
echo '<img src="'.generateImage().'" />';
In HTML5 you can put the base64 encoded image source in an image tag. You will just need a function to return that.
function getImage($file){
return 'data:image/gif;base64,' . base64_encode(file_get_contents($file));
}
Your img tag:
<img src="<? echo getImage('path-to-image.gif'); ?>" />
data:URI's but it's a terrible idea. Go with what @Sjoerd suggests
