功能概述 | Describe the feature

1. 邮件

邮件上传功能一直都有，但是不够全面，希望在后台添加邮件编辑框（支持HTML）

2. 图片

图片上传可以支持自定义图床等，更方便一些

Feature Overview | Describe the feature

1. Email

The email upload function has always been available, but it is not comprehensive enough. I hope to add an email editing box in the background (supports HTML)

2. Pictures

Image upload can support custom image beds, etc., which is more convenient

其实何止是这些功能需要在后台添加，其实所有需要靠yaml文件去完成的配置都可以展现在管理面板中，就像twikoo一样方便，也对代码小白比较友好。所以希望作者能够重视这个问题

In fact, it is not just these functions that need to be added in the background. In fact, all configurations that need to be completed by yaml files can be displayed in the management panel, which is as convenient as twikoo and is also friendly to code novices. So I hope the author can pay attention to this issue

1. 我们适配的都是一些免费的 Serverless 数据库场景，这些场景对读取次数有免费额度要求。使用环境变量的方式，能降低数据库读取次数。
2. 邮件模板编辑，这个其实可以找一些第三方在线服务使用，官方暂时可能还没有精力加这个
3. 图片上传是可以自定义图床的 https://waline.js.org/cookbook/customize/upload-image.html

1. We are adapting to some free Serverless database scenarios, which have free quota requirements for the number of reads. Using environment variables can reduce the number of database reads.
2. Email template editing. This can actually be used by some third-party online services. The official may not have the energy to add this yet.
3. You can customize the image bed when uploading images https://waline.js.org/cookbook/customize/upload-image.html

那就希望你们能把文档写的更详细些，要不然简短文字加代码真的看着吃力

Then I hope you can write the document in more detail, otherwise it will be really difficult to add short text and code

[lizheming]

这个没问题的。不过不同的人有不同的视角，文档已经尽我自己所能详细了。如果觉得有不详细的地方，可以提 issue 单独再咨询后帮忙补充到文档中

This is no problem. However, different people have different perspectives, and the document has been as detailed as I can. If you feel that there is something not detailed, you can raise an issue and consult separately and then help add it to the document
