Simple Solution:

I was stuck in this issue and after reading "@Michael Enriquez" post, I realized that this problem occurred due to wrong formatted image resource, I was worried how to check which file I saved incorrectly if I have so many image resources. So I just used a software named ImageOptim from AppStore which I normally use for reducing image sizes, so I dragged all the images to ImageOptim and I realized the wrong file, ImageOptim showed a cross sign on the wrong formatted image, then I changed that specific image to png and my problem is solved. I hope this solution will help you. Have a look at the snapshot below:
