Display the dimensions of an image

In this example we use the GetImageSize function again and this time we will display the width and height of the image . GetImageSize returns an array of 4 elements for this example the first two elements 0 and 1 are the ones we will be using . In index 0 we have the width which is measured in pixels and in index 1 we have the height again measured in pixels .

Once again you need the GD library installed and operating correctly .

Code :

<?php
//this is the image to check , change this
if($img = @GetImageSize("ihcomputing1.gif"))
{
//if image exists display the following information
echo "image exists , here is some info<br>";
//display width in pixels
echo "width = $img[0]<br>";
//display height in pixels
echo "height = $img[1]<br>";
}
else
{
//cant find image message
echo"image does not exist";
}
?>

Example :

 

image exists , here is some info
width = 468
height = 60
