I have a map in arcgis online with point data. Each of these points shows houses that have been destroyed by time. We have a wiki that tells the history about these houses, so I was wondering if there is a way to either link to the points location in the map (so I could just drop the link in the wiki), or extract a png file of an extent around the point and show that image in the wiki?
I would recommend you check out this post linked below Start ArcGIS Web Map Zoomed to Query
pretty much configure feature search in your web map for the points probably using the address field and then generate a url for that field with that address and use that url as the link in the wiki.
