Option to delete inserted images during case creation

[FlixProd]

Is your feature request related to a problem? Please describe. If you create a case and upload an image to it, there is no option to delete it during the process, e.g. because it's the wrong image. The only option is, that you delete it after the case is created, but than the notification is already sent with the image in it.

Describe the solution you'd like A little bin button next to the image name to remove the image from the case would be very helpful.

Thanks for your suggestion, maybe we can also include previews here, similar to the case view.
