Missy, I'm new to this also, but here's what I do: (1) keeping the window open to the team page, I open a new window in my browser and go to my shop's home page. (2) I click on an item, and when it comes up I go up to the address bar at the very top, highlight the whole address, and copy. (3) I close that window and come back to the team page, where I paste in the address. The picture won't show until I actually post the reply.
Good luck! I hope this procedure works for you!
