Using the mediaAttachmentUrl parameter with a fully qualified URL the attachment is part of the notification, visible, but not with an image item with the format item:MyImageItem.

Using:

actions.notificationBuilder("Bewegung am Briefkasten")
    .withIcon("letterbox")
    .withTitle("Briefkasten")
    .withMediaAttachmentUrl(items["SnapShotUri_Arenti_IN1_1"].state.toString())
    .addUserId(abc@def.de)
    .send();

The image described with the SnapShortUri (http://....) is shown

Using:

actions.notificationBuilder("Bewegung am Briefkasten")
    .withIcon("letterbox")
    .withTitle("Briefkasten")
    .withMediaAttachmentUrl("item:SnapShot_Arenti_IN1_1")
    .addUserId(abc@def.de)
    .send();

The image is not shown.

Expected behaviour

Both Uri and ImageItem should show the picture
