Changing Blog Name Issues

So I'm here trying to fix my blog because my posts weren't showing for months and months now for you readers when I update. Ever since I had changed my blog name from MsSpanish to SupaxKawaii this problem happened to me. It has happened to other people also. I advise you to make sure when or if you have a blog name make sure that's the name you want for your blog. I'm here using feedburner to fix it. I always wondered if my readers are even able to see my posts in there blog subscription because not a lot of people commented on my blog, it should be more views/comments. It is fixing but I'm now trying to make images show in the subscription feed.
