I usually use ArcMap to display photo attachments in a point layer. If I click the point with the HTML Popup tool, it displays a small photo corresponding to the point and I can click on it to open it in an external view where I can zoom in and out.
I can't find the equivalent in ArcGIS Pro. I can see the attachment using the Explore tool (in the Map tab), but then I can't open it like in ArcMap. I am stuck with the picture the size of a thumbnail.
How do I open the attached photo in an external viewer from the popup windows in ArcGIS Pro?
