Question

我正在使用下面的代码以html格式构建邮件，以便每天自动发送。我必须在邮件中包含 7张图片。图像存储在脚本所在的文件夹中的.jpg（我也尝试过.png）中。

我遇到的问题是图片显示不正确：如果我尝试将电子邮件发送到gmail地址，我可以正确看到所有图片，但是每当我将电子邮件发送到企业电子邮件时，都可以看到某些图片其他则不是（我尝试使用Outlook和Web Outlook尝试从两家不同公司发送电子邮件）。

所显示的图像是随机变化的，但是可见的图像似乎总是四幅。有谁知道这可能是什么原因以及如何解决这个问题？非常感谢！

这是我的代码

names = ['1.jpg','2.jpg','3.jpg','4.jpg','5.jpg','6.jpg','7.jpg']

msg = EmaiMessage()
msg['Subject'] = """AAA {d}-{m}-{y}""".format(d = day.day,m = day.month,y = day.year)
msg['From'] = "test@gmail.com"
msg['To'] = "test@gmail.com"
image_cid1 = make_msgid()
image_cid2 = make_msgid()
image_cid3 = make_msgid()
image_cid4 = make_msgid()
image_cid5 = make_msgid()
image_cid6 = make_msgid()
image_cid7 = make_msgid()

msg.add_alternative("""\
