Random images from imagelist

Trying to make a game where explosions randomly appear on the screen using visual studio. I figured out how to make a single picture change location on the screen. So, I wanted to make the illusion of an explosion using imagelist. When I try to do it I get an error on my visual studio when I try to use Location. Location is underlined and say the following "ImageList" does not contain a definition for "Location" and no accessible extension method "Location" accepting a first argument of type "ImageList" could be found (Are you missing a using directive or an assembly reference?) I wanted to add more explosions on the screen .

        }
        int num = 0;
        void Randompics()
        {
            int a;
            Random rnd = new Random();
            a = rnd.Next(30, 450);
            boom.Location = new Point(500, a);
        }
        void Explosions()
        {
            /*
            int a;
            Random rnd = new Random();
            a = rnd.Next(30, 450);
            symbol.Location = new Point(500, a);

            imageList1.Location = new Point(x,y);
            boom.Image = imageList1.Images[num];
            if (num == imageList1.Images.Count - 1)
