Hi I'm building a crowdsource storymap. We hired an illustrator to create the image for the splash screen. Before I began this process I inquired about the size and aspect ratio for the image and was told that the art must be at least 2000x1000 px and that the software would adjust to the image (at least that's my memory) I have uploaded the draft and it cuts it off on the sides. Is there something I can do to fix this? Help! Here's a link to the storymap.
