            states3.ImageIndex=1;TreeNode states4 = rootNode.Nodes.Add("California");
            states4.ImageIndex=1;// Create siblings nodes for the Child nodes TreeNode child = states1.Nodes.Add("Rochester");
            child.ImageIndex=2;
            child =states1.Nodes.Add("new York");

i want to add animated gif icon at tree node instead of ico file. how can i do it. the most important part is animated gif image should play when i will run my apps. looking for best solution instead of developing custom treeview. thanks
