On other apps, when an image or video is posted I can long press on it to copy a direct link to it. The best I could find in Voyager is to copy a link to the lemmy post or open the post in a browser. This makes it hard for me to share memes with friends who don’t use Lemmy. But maybe this feature already exists and I don’t know where to find it. I just started using Voyager yesterday.
Click the image such that it goes full screen. Once the image is in that state (no visible ui, etc.) then I am able to long press for copying/sharing. At least, for me this works.
