Is your feature request related to a problem? Please describe.
In the gallery view, only pagecovers can be selected as an image. Furthermore, there is the possibility to create an attachment-picture as a relation, but without showing the picture.
Describe the solution you’d like
Option a) A new relation type that behaves exactly like the picture block. When selecting a picture, the picture will be inserted directly into the content. Furthermore it should be possible to select the picture relation type in the gallery view as preview image.
Option b) The relation type picture should be extended by a dynamic reference. It should be possible to select the attachment relation field as a dynamic picture reference. If a picture is added as an attachment, it should also be displayed in the picture block. In addition, the attachment relation type should be selectable in the gallery view.
Describe alternatives you’ve considered
There is no workaround.
