Разобрался ,
и даже работает :

    selector++;
    
    if(selector == 1){
        select = orig_size;
        txt_show = "original_pic_size";
                    try {
    fso.DeleteFolder(set_path + "*.*");
    } catch(e) {};
window.SetTimeout(function () {
window.Reload();
}, 4250);

        };
    if(selector == 2){

        select = medium_size;
        txt_show = "medium_pic_size"; 
                    try {
    fso.DeleteFolder(set_path + "*.*");
    } catch(e) {};
        window.SetTimeout(function () {
window.Reload();
}, 4250);

        };
    if(selector == 3){
       
        select = small_size;
        txt_show = "small_pic_size";
                    try {
    fso.DeleteFolder(set_path + "*.*");
    } catch(e) {};
        window.SetTimeout(function () {
window.Reload();
}, 4250);
        selector=0;
        
        };
