Help! Is our she a he?!
Hi Yoder welcome to BYC.
To upload a picture click on the picture icon. On my computer letting the mouse indicator hover over the icon brings up the words "insert image". That is the one you want to click on.
Clicking on that should result in a dialog box with a button at the top that says "upload files".
From there you will have to find the pictures that are saved on your computer. Of course then you select the picture you want to share.
Selecting the picture should pull up a dialog box where you choose the size you want the picture to be and then click on the submit button.
Since I only upload from my computer and not other sources I don't know any other method.
