This script is equivalent to write the following html code:

<script src="/json?callback=loadJsonPhotos"></script>

That's a little snippet of code to set the src (source) attribute of a Javascript include tag to /json?callback=loadJsonPhotos. Once that line of code runs, the browser will fetch the data from that URL and execute the script that returns. The data that script returns will be wrapped in a function like so:

loadJsonPhotos({data: "blah"});

All you need to do to use that data is write a function called loadJsonPhotos that will be called once the data has loaded.
