This is a very useful function in PHP. PHP provides function to get the width and height of an image. The
getimagesize() function will determine the size of image file including flash file(swf).

Code

This is a sample code, change image_name to your image name and test it!

<?php

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

echo “Image width ” .$width;
echo “<BR>”;
echo “Image height ” .$height;
echo “<BR>”;
echo “Image type ” .$type;
echo “<BR>”;
echo “Attribute ” .$attr;
