Describe the bug
Image is not visible when uploading. Problem is shown in gif.

Has anyone solved this?
The same for me. It seems that the majority is using vichuploader and liip extension. Luckily it's just 'visual' and the image is upload and the entity is well saved

The file input is the most gnarly of the bunch and requires additional JavaScript if you’d like to hook them up with functional Choose file… and selected file name text.
This means that we must add the missing JavaScript code for it to work properly. Likely here in EasyAdminBundle.
