Can this "if" statement be simplified?

I have an if statement that verifies when <img> tag is missing dimensions (width/height) or if they are blank (width=""/height=""), for example:

<img src="http://ift.tt/2k9LMhL" alt="Blank width/height" width="" height="">
<img src="http://ift.tt/2k9LMhL" alt="Blank width" width="">
<img src="http://ift.tt/2k9LMhL" alt="Blank height" height="">
<img src="http://ift.tt/2k9LMhL" alt="No width/height">

The if statement below works for me. However, I wanted to know if it's possible to simplify the logic that I am using:

if (
    # There is no width
    ! in_array( 'width', $img[1] ) ||
    # There is no height
    ! in_array( 'height', $img[1] ) ||
    # The width is blank (width="")
    ( in_array( 'width', $img[1] ) && in_array( '""', $img[2] ) ) ||
    # The height is blank (height="")
    ( in_array( 'height', $img[1] ) && in_array( '""', $img[2] ) )
) {
# Code here...
}
