有没有办法在 Email 通讯/签名中隐藏被阻止的 html 图像？

Question

Ive created an email signature with a few images. Most email programs block these or ask for permission. In this case the Images are displayed by a blank box. Is there a way to get rid of said boxes if the client blocks html?

Answer 1

You can try to insert images as base64 Data URI (if your images are relatively small). You can use this online converter to generate Data URI for your images.

Here is an example:

<img src="data:image/png;base64,iVBORw0KGgoAAA
ANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4
