I imported a legacy graph https://legacy.graphcommons.com/graphs/b5eec0ec-8ac5-4237-9b9f-d8457cc27b85# to the new version. I then chose "display node images" in the option pannel. All nodes have images but only one got displayed. You can check that the images exist in the nodes info. https://graphcommons.com/graphs/b5eec0ec-8ac5-4237-9b9f-d8457cc27b85
