小白求助：请问怎么爬取img标签下的src地址？

Question

https://www.gooood.cn/sl_release-apartment-by-pascali-semerdjian-arquitetos.htm

img这个标签好像没有独特的元素去定位，比如每张图片的img标签下的class属性值都不同，只会用find_all('a', class_='colorbox_gallery')到，要取出里面img里的src就没招了，求指导

然后，下载图片的过程中，有时候会遇到UnicodeEncodeError: 'gbk' codec can't encode character '\u0131' in position 7: illegal multibyte sequence
图片下载就中断了，有解决的办法吗？

import requests
from lxml import etree
url = "https://www.gooood.cn/sl_release-apartment-by-pascali-semerdjian-arquitetos.htm"
r = requests.get(url)
print(r.content.decode())
html = etree.HTML(r.content.decode())
imgs = html.xpath("//img//@src")
n = 1
for i in imgs:
print(i)
response = requests.get(i)
img = response.content
with open("./imags/{}.jpg".format(n),"wb") as f: #需要在当前目录下建立imags文件夹
f.write(img)
n += 1

#亲测运行正常
