What would I have done without you guys? Many thanks to you, @alibyte . I tried imgur about 30 minutes earlier, but didn't get the desired results. Cubeload.com did the magic for me. I have been able to use it to post the map of my beautiful country in my blog https://steemit.com/nigeria/@maryfavour/about-2-55-of-the-world-s-population-are-nigerians . My sincere appreciation.
