Validation for image upload disappears when fill the body input

Describe the bug
When creating a new blog the validators for required fields appear at the bottom of the page. They should disappear when the required fields are filled out. However, when you fill in the body input the validator for the image upload disappears.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Add new blog'
2. Fill in header subheader author and body
3. Scroll down to just above the submit buttons
4. See that the validator for the image has been hidden or disappeared even though no image was uploaded

Expected behavior
Image validation should disappear after image was uploaded.

This was noticed when testing the pull request that fixed "blog not submitting when tag field empty". This was I think an issue before that bug fix tho because no code for image upload was touched from viewing the edits

从“Add new blog”表单开始，在不上传图片的情况下填写 header、subheader、作者和正文，以复现该问题。跟踪表单验证行为，并确认图片验证器会一直显示，直到上传图片为止，同时包括现有的必填字段验证流程。
