Hi, I'm leading a class at USC, and one of our projects is to have students create a Story Map on a water-related topic. Most are creating Map Tours. My question is this: is there a way to upload a batch of photos after we have already done the initial upload of photos? We are uploading an album of photos from flickr, and then we get to the Builder Mode page to edit and add to the Story Map. But from here, the "Add" button only lets us add one photo at a time, and it is involves multiple steps, including copying and pasting the URLs for each new photo and its thumbnail, whereas the initial batch upload takes the photos from flickr and creates thumbnails for them.
