I've got source image https://www.imageupload.co.uk/image/ZRor and an image to compare with the source https://www.imageupload.co.uk/image/ZRol
Is there a way in PHP to check if the source contains this image and return it's left and top position related to the source?
Try out Imagick::compareImages function, http://php.net/manual/en/imagick.compareimages.php
It will "Returns an array containing a reconstructed image and the difference between images."
That should work.
