Minify the HTML Output kills dynamic image processing

Hi support,

Thanks for a great plugin that really speeds up the user experience!

On my site I generate images dynamically which is working fine until I enable “Minify the HTML output”. The image is generated serverside and returned using php. An example URL would be:
https://staging2.navnelabels.nu/wp-content/plugins/b2t-labels/b2t-labels-preview.php?line1=preview&line2=text&line3=%20&font=Roboto&color=000000

and the html in the webpage would look like:

The simplified PHP code looks something like this:
$result=Imagick generated image
header(‘Pragma: public’);
header(‘Content-Type: image/’ . $result->getImageFormat());
echo $result;

Please feel free to contact me for more information or if you need to test it.
