Help adding custom image to follower alert


I am having trouble adding a custom image to my follower alert on nightdev. Everything seems to work until I test out the alert, and the image does not pop up.

I’m wondering if some one could walk me through step by step, as I am not very tech savy.

Here is the image link for consultation

Thanks for any help you can offer!


As stated on the upload form, the max size is 580x110 pixels. Your image is far outside this boundary.
