Once you choose the 2 picture frame, head to the Library tab (on the left bar). You can drag on the images from there.
By the way, you can still access our old version of Ribbet if you’d like to. It’s now available as a program from ribbet.com/download. It’s identical to our previous (Flash) version and once installed will add a Ribbet icon to your Windows desktop / Mac icon dock. You can launch Ribbet from that icon (no need to return to our website) and also sign in with your existing Ribbet account.
If you have any further questions, please let us know.
