Images in plugin interface

How i can load image in interface plugin?

I tried using standard methods by type: <img src="images/test.jpg" id="11">, But nothing happens.
I also tried using webpack, but for technical reasons it doesn’t work for me.
Is there any way to upload an image to the plugin interface? Or other programs like webpack?

Or encode your image in Data URL and embed it in the code.

Thank you very much, it works
