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?

  • You can't overcome a security feature like image block. It is set by administrators and users. You could style the `TD` and the `ALT` to offer an alternative styled signature to display so it's not a blank box. This would be overlayed with the image you want to show if images are not blocked by default. – gwally Mar 15 '21 at 19:36

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
//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU
