Regex to validate image urls with query string

I want to validate image urls, few with query string and few without it. https://images.company.com/img/800X450/vehicle/201610/858823_589_1475572549658.gif?bg=000000&wmi=n

http://images.company.com/img/800X450/vehicle/201610/858823_599_1475572549658.jpeg?bg=000000&wmi=n&pne=ur

http://images.company.com/img/800X450/vehicle/201610/858823_599_1475572549658.png

So basic thing is to validate any image with jpg|png|gif|jpeg extension, with or without query string parameter.

I tried using Matches(@".(?i)(jpg|png|gif|jpeg)") regex.

But problem is it is validating images like: http://images.company.com/img/800X450/vehicle/201610/858823_599_1475572549658.pngg OR http://images.company.com/img/800X450/vehicle/201610/858823_599_1475572549658.giff

How can i validate if url has exact extension jpg or png or gif or jpeg and optionally some query string parameter after that?

Assert that the listed file extension must be followed by a query string or end of string:

(jpg|jpeg|gif|png)((\?+*)?$|$)
