Well, when creating interfaces I usually group the wireframe elements together to keep everything aligned and organized, as well as to speed up the process of hi-fi design and prototyping, and to finalize the hi-fi design I prepare materials as arts in the style of the app I’m designing, to then insert into the project later, however, Figma still does not have the option to drag an image into a selected element, as shown in this video within XD where it is possible to do this with elements grouped or not.
That’s why I suggest adding this possibility, so that I don’t have to ungroup everything or keep resizing the images that I’m going to use within the groups that I create, and much less, being limited to using plugins to add images.
