Help needed with 기사 formatting!

So. On the side of an 기사 it explains that if 당신 업로드 some bottom images, 당신 can then embed them in the article. However, I am uploading 이미지 and trying to embed INTO the article, but all they do is show up at the very bottom.

Am I doing something wrong? I'll have a line of text that says in the portion where I want the 사진 to be placed, and still the 사진 will be stuck at the bottom. Help me pls!
