Hello, I'd like to create a thread and post a picture as an attachment that would be visible to all EC members that are logged in, but not to people who are just browsing the forums unregistered/unlogged. I guess what I have to do is to upload that picture in one of my albums (public) and then put the link to it in the thread? I know it probably depends on a forum's settings, because I remember that on different message boards I could see attachments either in full view (without having to log in) or just a thumbnail. On EC, would thumbnails still be visible to users that aren't logged in?
I *think* you just need to hit "Go Advanced" and attach the image. Edit: Checked. Apparently I was correct. No thumbnail there.
I don't know offhand if thumbnails/attachments are visible to visitors, but if you don't want non-users to see your image, then yes, uploading it to a publicly visible album and posting a link to it in the thread is the way to go. Only members who are logged in can view albums.
Note that if it's a picture of yourself, it can't be posted on the forum. In that situation, you'd want to put it in an album and post the link.
