How to display base64 images in gmail? [duplicate]

Question

I'm sending base64 encoded images in a markdown newsletter to different email services from a rich text editor. Every service renders the images properly except gmail. Instead it displays the base64 string:

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAACLQAAAxOCAYAAAD0p7d8AA...

The main SO thread regarding this problem does not provide a solution, as can be seen in the comments of the accepted answer.

How does one display images from a data string in gmail? Is it possible to insert a transformation layer to make it work? (I can't believe gmail doesn't support this after 6 years)

Answer 1

Gmail does not support embedded Base 64 images (see Can I email). I believe this is for general security reasons. You either need to generate your image server side. Or send it as an attachment (like in the other post you mentioned).
