Creating a map with an image background layer

[kevalpatel26]

Hello, 

I have been following this guide to create a custom map using an image background layer. 

https://help.qlik.com/en-US/sense/February2021/Subsystems/Hub/Content/Sense_Hub/Visualizations/Map/m...

The image dimension is 886 x 749, what would be the top (latitude), left (longitude), bottom (latitude) and right (longitude)?

Thank you!
