==Photos and links in these PA marker lists== 
 The PA state markers are often different than the NRHP designations or other local designations (e.g. Pittsburgh Landmarks) in that they often refer to people, places, events, etc., not just structures. The physical evidence of these historic events are often long gone leaving nothing but empty fields or unrelated new structures.  

 The PA  plaques and their text are copyrighted so using images whose primary subject is a plaque is a copyright violation and is not appropriate for Wikipedia in list-type of article such as these (see WP:NFLISTS). The PA historical plaques can be included in a picture (as an extraneous part like this photo here), but the cannot be the main subject of the photo (like here...this photo is likely a © violation, tagged wrong & shouldn't be at Commons). The plaques fall under the same category as sculptures (see Freedom of panorama#United_States and Template:Non-free 3D art). So please keep this in mind when you are adding photos to these tables.  

 For these reasons, some of the images in the table are likely to be contextual just like the markers themselves. Often a marker is about a person, not the person's birthplace or workplace in particular although it might be near such a location. Therefore, an image of a person or event is probably appropriate for use in the table. This is quite different than the NRHP lists that most editors are familiar with, but those lists are most for historic places and structures that have maintained their integrity, unlike the PA markers.  For an example of how images can be used to populate a PA historical marker list, please see List of Pennsylvania state historical markers in Allegheny County. 

 Also, before Wiki-linking a marker title to an article, it is probably good check the marker context of the marker by reading its text after finding it at the Pennsylvania Historical and Museum Commission's database (here). Sometimes the topic of the marker is not obvious from the title.
