I recently had a lookup I needed at the cemetery. I called them on the phone and they were very helpful with burial info, they even sent me a map of the cemetery with my burial locations marked on it. Their phone number is listed on the website bohemiannationalcemeterychicago.org

If you are looking for a picture, once you know the burial location you can try this site for a volunteer to take the picture for you http://www.raogk.com/listing.htm

I hope this helps
