Idea: perform special attachment management in the background. Associate an image with a post. If the post is not published successfully, it means that the uploaded image is not associated with the post, and then delete the image. You should always pay attention to attachments. Many people use this vulnerability to publish illegal images and then call them from your server. This may cause you to spread the event.

The user uploads images in a temporary directory.moveOrcopyTo another directory, and then the server hasshellThe temporary directory is cleaned regularly. I wonder if this answer is satisfactory?

In this case, we should consider whether the server processes the uploaded files in the cache or in the directory.
Logically, users are generally given the chance to choose a draft box.

The reason why an image is uploaded asynchronously (indicating that the image has been uploaded successfully) is to use the image, indicating that you have already obtained the image path. Post publishing is a submission process, if a post is not published, it means that the post is not submitted successfully. If the post is not submitted successfully, you can do something (for example, delete the image in the corresponding path). This is just an idea, you can try it.

The server script regularly checks the deletion, or you can record it and request the server to delete it at a specific time.
Generally, it's okay to upload a few images.
