好的，我可以帮你将这段代码改成多线程的。你可以使用Python中的`threading`模块，下面是修改后的代码：

import requests
from lxml import etree
from selenium import webdriver
from selenium.webdriver.common.by import By
import os
import time
import threading

url = 'https://www.ivsky.com/' #目标网址

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36'
}

path = r'C:\Users\yangyuhuan\AppData\Local\Google\Chrome\Application\chromedriver'

driver = webdriver.Chrome(executable_path=path) #申请驱动器

if not os.path.exists("./images"):
    os.mkdir("./images") #创建结果文件夹

def download_image(src, name):
    img_url = "https:" + src
    res3 = requests.get(img_url, headers=headers).content #获取图片的二进制文件
    time.sleep(3)
    print(f'正在下载：{name}')
    with open('./images/' + name + '.jpg', 'wb') as f:
        f.write(res3)

def download_page(page):
    url = f"https://www.ivsky.com/bizhi/index_{page}.html"
    driver.get(url)
    response = driver.page_source  # 获取网页源码
    html = etree.HTML(response)# 对网页结构进行解析
    time.sleep(3)
    src_image_result=html.xpath('//div[@class="il_img"]/a/img/@src')
    name_image_result=html.xpath('//div[@class="il_img"]/a/img/@alt')
    threads = []
    for src,name in zip(src_image_result,name_image_result):
        t = threading.Thread(target=download_image, args=(src, name))
        threads.append(t)
        t.start()
    for thread in threads:
        thread.join()

for page in range(10):# 页码
    download_page(page)
    
driver.quit()

在修改后的代码中，我们将下载图片的`download_image`函数和下载每个页面的`download_page`函数分别放到不同的线程中执行。同时，我们使用线程列表`threads`来保存每个线程对象，使用`thread.join()`方法来等待所有线程执行完毕后再结束程序。
