Add a tool sidebar help image in ArcGIS Pro 3.1.4

[MattHowe]

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.

I wonder if it would be worth submitting a case to Esri Support to see if it's a bug.

Is this the behaviour you note?

check the toolbox you created to see if it appears.

I just checked one of mine (follow 1, 2, 3)

and it appears in the tool help, but doesn't show up in the tool sidebar help when editing the toolbox metadata, but it does when when you just view the metadata

So my experience is:

1. Add an image to thumbnail and you will see the image when you view the metadata it catalog view.
2. Add an image to Tool sidebar help image and although you see it when in edit metadata mode you never ever see it when interacting with the tool! It was something that worked well in ArcMap but seems to me to be totally defunct in ArcPro.
3. With the release of 3.3 they added the ability to add an illustration to a tool, you access it via tool  properties and that shows up an image when you hover over the ? in the blue circle on a tool (top-right).
