Perhaps a better way would be to download a KMZ file that can be used in Google Earth. On the Google Earth Community Group (get the KMZ file from there), Burnham says of the KMZ file:
It is a compilation of the 25000+ locations we have listed on the Megalithic Portal. Each entry includes summary descriptions and a thumbnail image, where available.The links do provide good information and multiple pictures where available. The sites are organized according to what they are in 50+ categories: temple, palace, tomb, mound, cave, pyramid, etc.
In terms of sites connected with the Bible, it's a mixed bag, but this is an ongoing work, and users can add their own sites and pictures. E.g., in the screen shot of west-central Turkey above, there are some links for Ephesus, Miletus, Sardis, Smyrna, Laodicea..., but not for Philadelphia or Colossae. In Greece, you can Philippi and Corinth but not Thessalonika.
In any case, it's worth getting the KMZ file and adding the web site to your list of resources.
