Please help! How to get rid of attachments?

[The Hidden Owl]

I hate when I have a picture on my post, I backspace it, and post a new one that it shows below in attached images. How do I get rid of those? ;n;

you have to go into edit post, advanced mode, then "manage attachments"
it happens to me all the time trust me its the worst, just x them out and theyll go away <:
