Seán Doran has made a cool visual index to the images that JunoCam took during Juno's first 12 closest approaches to Jupiter. The resolution on the click-to-enlarge version is high enough to clearly see which features Juno approached close to as it neared Jupiter's equator, but not quite high enough to see polar features. For those, you can go look at the version that Seán posted to Gigapan, which has lots more pixels (more than 3 billion!).
If, like me, you mostly can't name features in Jupiter's clouds other than the Great Red Spot, you will find John Rogers' maps and commentaries useful. Here is a list of all his posts about Juno's images from Perijoves 1-10, and here is where Rogers is building a list of posts for Perijoves 11 and beyond. Rogers has also posted a handy list (PDF) of the dates, times, and geometric information for perijoves 1-22.
