The PB image link needs to end at "JPG", take the ?width=960&height=720&fit=bounds off the end and you should be good. Thanks for sharing!
Thanks for your help, Squidge. I tried that with the first half dozen shots and it still didn't embed properly. I've been using PB for years and never had a problem. They updated their platform/site recently and now I can't get the damned thing to work properly...
