Hi @mlchrt
I hope you are doing good today.
With a single upload file, this will be not possible. However, you can set up file upload as multiple, which allows seeing small images. With the below code you will be able to set up image box as full width, remove file name, and leave X to remove the image.
Note to limit this muliple upalod to 1 file in settings.
#forminator-module-185 is your form ID which you can find in page source.
#forminator-module-185 .forminator-uploaded-file--image {width:100%; height:400px;}
#forminator-module-185 .forminator-img-preview {background-size:contain;}
#forminator-module-185 .forminator-uploaded-file--text {display:none;}
Kind Regards,
Kris
