Great bag. To post to your Facebook group, write your post comment and where you do that, you will see a small icon in that area that says photo. Click on it and you can pull up your picture and attach it. I do mine from an IPad, so my pics are either on a camera roll or an album. If you are using a pc, your pic should be uploaded to a folder you have created for pics. It's similar to how you put your pic in here.
