Adding pictures in tasks

Is there a way to design tasks and add images to it?

Hello Raghees,
You can return any HTML elements in the task bars. To do that, you need to use the task_text template:

Or you can specify the class name in the task_class template and add images via CSS:

Here are examples of how it can be implemented:
