Question

I have a script that creates an image. I have to make a common format like GIF, JPEG or PNG out of it and convert it to base 64, later on.

When doing this, I do not want to save the image on the server, nor I want any browser output.
So imagepng() seems not right command for this.

Any ideas?

If all else fails, you can always do this:

ob_start();
imagepng($resource);
$png = base64_encode(ob_get_clean());
