if not enable option "Download images alongside markdown files", download markdown file's images would be something in markdown file like:
![Image](https://mmbiz.qpic.cn/mmbiz_gif/0UdhCqGulicdW4XSJpnW7ZAoZGPRNe4icfibylabw3GfUTtKRHo3v2TwxBCcrSnwzV4wN8LiaQ5oib4hJKa3sMeYnXA/640?wx_fmt=gif&tp=webp&wxfrom=5&wx_lazy=1)

if enable option "Download images alongside markdown files", then those images would point to same name:
![Image](_resources/%E5%B9%BC%E5%84%BF%E5%9B%AD%E8%BF%91%E8%A7%86%E9%98%B2%E6%8E%A7%E6%89%8B%E5%86%8C/640)
![Image](_resources/%E5%B9%BC%E5%84%BF%E5%9B%AD%E8%BF%91%E8%A7%86%E9%98%B2%E6%8E%A7%E6%89%8B%E5%86%8C/640)

Hope it could be solved as bug or new feature, Thank you.

Ah, I see what's happening here. Both images do, in fact, have the same name. If you look at the URLs, the file name for both is "640". So I'll need to append a number to make the filename unique. In this situation, you'd likely end up with 640 and 640(1) (or maybe 640.1).

🤔 I might also want to see if the file is missing the extension, and if it is like these are, try and ascertain the correct extension and append that.
