Nominatim Contain tiles images ?

Dear Arun KMP: If everyone setting up a Nominatim or tile server were to ask this many questions, we couldn't do anything else besides writing answers. Your questions show a lack of understanding of basic OpenStreetMap services. This is nothing to be ashamed of - it can be cured by reading the available documentation, most notably switch2osm.org which has already been mentioned to you, as well as several existing answers in this help system, and wiki.openstreetmap.org. After you have read and understood the available documentation, then if you still have questions, we will be happy to help you. But we cannot replicate the available documentation piecemeal in this forum.

In response to your question: Nominatim is a geocoding server, not a tile server. If you want a tile server you have to set one up separately. Don't be confused by Nominatim returning a web page with a map on it; the tiles on that web page come from openstreetmap.org.
