I'd like to add images to our custom tools' help pop up windows to provide users with a description of what the tool does. When I try to add an image, it looks like it gets added to the metadata but never displays in the tool help pop up. Is this a known bug in 3.1.4? I've tried varying different resolutions of images including the recommend 200 x 133 for a thumbnail.
I know this has worked previously in a previous version of ArcGIS Pro.
