Hi Cynthia: are you a paying member, because that is how you get a portfolio. If you have signed up, you will have a welcome email from them. I had to read lots of the help sections because I had some trouble figuring it out, but now its so easy. On the bottom left, there is a spot called Image tools. You click on art case/portfolios, and that takes you to a spot where you can add your images. It does a good job of leading you through things. As for the certificates, when you have a webpage on ebsqart, you get all the benefits, which include being able to create the COA's. Sorry for the long post, this may end up a novel if I don't stop now.
Let me know how you make out. 😄
