Welcome to Stovebolt.com, Lindsay
One way to post photos it to use that "attachments" feature that appears below the Post/Edit window, when using the Full Editor option.
However, I do not think that photos can be attached in this forum (the Welcome Center)?
In the Welcome Center, I think you have to provide a link to a photo hosted elsewhere (like Photobucket or Google Drive or . . .). Many of those hosting sites cause problems by loading up the viewer's screen with advertisements.
