Well I finished my Email Advertisement and I uploaded it to Github, which is great but then when I loaded it up the project I had no Image.
I am not sure what the issue was exactly because it was hosted on postimages.org and it appeared the problem is on their end. I checked my other images from older projects that used postimages.org and they worked like normal.
Well my solution was to wait a few days and see if it loads like normal again which it did. Although in the future I will host my images on my domain and also use google drive. I will look into other hosting solutions because I do not need my images not loading on my projects.
So for the final piece of this is to make sure when you host your pictures make sure it is a reliable hosting service. Although sometimes things go down no matter what you atleast want to make sure you get or provide the best service.
