Hello,
The problem is that the images you are adding don't have the same dpi. So as you are not forcing a dpi, phpdocx uses the dpi from the image.
This image:
https://dev-or.s3.amazonaws.com/dev/Slide/9379/iconlist.jpg?1331844575
has 96 dpi. And this is a PNG image, not JPG; we recommend you to use extensions with the same mime types than images.
And this image:
https://dev-or.s3.amazonaws.com/dev/Slide/9380/iconlist.jpg?1331844575
has 72 dpi.
You can force the dpi value to get the exact image size, regardless the dpi of an image:
$image = array(
'src' => 'image.jpg',
'imageAlign' => 'center',
'height' => 216,
'width' => 288,
'dpi' => 72,
);
$docx->addImage($image);
Regards.
