I vote for photo insert option. meaning i really dont feel like uploading a photo to my domain and then have to insert into a post from my domain... You can upload photos to every module in dolphin. Might as well include this for forums.
I suppose file attachment will have to do if i must.
File attachments and/or Dolphin's photos module may be used for that. For now, I think that maintaining one more photos repository for Forum uploads, plus functionality to make thumbs, rescale, convert, etc. would be too much.
