Post does not display the new picture and ruins the new one

I deleted the old picture so I would use less space, and the post does not display a picture at all in the thread "Skins and Champion Concepts". In addition to this, the first, new picture fails to display when one clicks on it. What I had to do to be able to display my new picture, was that I needed to upload the old again as the first picture... Why?!? Now I have one unnecessary picture taking up my post, and my post does not display a picture in the thread section, making it less desirable to check out.

Please fix this.
