| 23 | +## Description |
| 24 | + |
| 25 | +This knowledge base article answers the following questions: |
| 26 | + |
| 27 | +- How can I set a background image for the Blazor Map component? |
| 28 | +- Is it possible to overlay markers on a static image in Blazor Map? |
| 29 | +- Can I use a custom floor plan as a map in Blazor? |
| 30 | + |
| 31 | +## Solution |
| 32 | + |
| 33 | +The solution depends on whether you want to show a static Map or if you want to support panning and zooming functionalities. This knowledge base shows the first option: |
| 34 | + |
| 35 | +* [Static Map](#static-map) |
| 36 | +* [Pannable and Zoomable Map](#pannable-and-zoomable-map) |
| 37 | + |
| 38 | +### Static Map |
| 39 | + |
| 40 | +This method is ideal when using the Map in a static context without the need for dynamic panning and zooming. In this case, you may use CSS to target the wrapping element of the component and set your image as a background image. |

| 83 | + public double[] LatLng { get; set; } |
| 84 | + public string Title { get; set; } |
| 85 | + } |
| 86 | +} |
| 87 | +```` |
| 88 | + |
| 89 | +### Pannable and Zoomable Map |
| 90 | + |
| 91 | +If you want to support panning and zooming the custom image in the Map, you will need to mimic the default Map behavior targeting the [Tile layer]({%slug components/map/layers/tile%}). For that purpose, divide your image into small pieces - separate images that build up the whole picture and serve them to the Map as tiles following the Tile layer specifics. |
