I have recieved many queries from people asking , how can they resize image in the fly using php.
Today I will explain how we can do it , but before we jump into code it has some prerequisite and constraint:
1) GD library should be installed on your server.
2) It works with only jpg and gif images.
IF you wondering how to make sure GD library is installed on your server , use the code below-
echo ” Status of GD support on your server: “;
// Check if the function gd_info exists (great way to know if gd is installed)
$gd = gd_info();
// Show status of all values that might be supported(unsupported)
foreach($gd as $key => $value)
echo “–” . $key . “: “;
