Hi scrappygirl,
click on quick reply
click on go advanced (below the quick reply space)
there is an option to upload an attachment from your computer/device in there. If your picture is too big it won't attach. Once you click on your file, you need to scroll across the page to get to the upload link. click it. That will post the pictures but you won't see them until you submit your reply.
if you search on "how to post pictures" in the quilting board search bar, you will find other instructions. I am looking forward to seeing your quilt.
