Możesz użyć getimagesize funkcja taka: 

list($width, $height) = getimagesize('path to image');
echo "width: " . $width . "<br />";
echo "height: " .  $height;

Używając funkcji getimagesize możemy również uzyskać te właściwości danego obrazu - 

<?php

list($width, $height, $type, $attr) = getimagesize("image_name.jpg");

echo "Width: " .$width. "<br />";
echo "Height: " .$height. "<br />";
echo "Type: " .$type. "<br />";
echo "Attribute: " .$attr. "<br />";

//Using array
$arr = array('h' => $height, 'w' => $width, 't' => $type, 'a' => $attr);
?>


wynik taki -

Width: 200
Wysokość: 100
Typ: 2
Atrybut: width = " 200 "height =" 100 "


Rodzaj obrazka -

1 = GIF
2 = JPG
3 = PNG
4 = SWF
5 = PSD
6 = BMP
7 = TIFF (intel byte order)
8 = TIFF (motorola byte order)
9 = JPC
10 = JP2
11 = JPX
12 = JB2
13 = SWC
14 = MFF
15 = WBMP
16 = XBM
