Improve insert picture dialog for ArcGIS Pro

[DuncanHornby]

ArcGIS Pro 3.3 introduced presentations. You can insert an image into a presentation page. The navigation dialog shows a generic icon and a path to an image, this I show below:

It would be good if this navigation dialog actually showed a thumbnail size picture of the image to help user choose the correct image.

[Moderator note: this is not specific to inserting pictures in Presentations. There are other workflows that use the Insert Picture dialog (e.g. layouts) where this idea is applicable.]

Pro does not allow you to see a preview of picture icon for point symbology like ArcMap used to.  Most  software allows previews of pictures when inserting them.  Pro just shows the file location/URL of the picture.  Unless you know the actual name of the picture icon in the folder, you can't be sure that you are using the correct picture icon.  This basic functionality is necessary.
