As we love to upload images in both Opencart admin end and front end then we should know about how to use opencart default image library.Opencart has been changed some codes in image library file of\u00a0version 2.1.x.x and today we are going to learn about the object constructor differences between Opencart version 2.0.x.x and version 2.1.x.x image library file.<\/p>\n
Version 2.0.x.x –<\/p>\n
when we make an object of image class then this constructor is called<\/p>\n

width,height,bits and mime values are stored as indexes of class global variable in Version 2.0.x.x but in Version 2.1.x.x these values are used the class global variable to store the value.and we can get these values by calling these functions<\/p>\n
