In your post or reply, you should see a button to "upload" file. Press that, then you have to locate the file on your device. Select and upload. You can then select the size as full or Thumbnails.Kind of remind me of my 2015 Chieftain with sidecar (springfield blue and ivory). If there is a tutorial on how to post Photos I will post a picture of mine, or if someone could include how to in a reply.
