Missing pictures in published Story Map

I have just returned to a StoryMap, created in ArcGIS Online, that I published over a year ago, but use frequently to share with collaborators. However, it now appears that one of the images is missing (forth panel): https://storymaps.arcgis.com/stories/f540b764fc6c47db886b38515560852f

I am not sure where this image has gone, it is likely the image was linked from Pinterest. There is a thumbnail on the edit page, but no other information. Any ideas how to get this image back?

If I right-click on the missing image, I can copy the image URL (https://www.kew.org/sites/default/files/styles/header_style/public/2020-09/Colombia-upf.jpg). Navigating to that site in a browser returns a page no longer exists message, so it looks like they may have deleted that image.
