A unique image URL is generated for you which will automatically output the geo based image based on visitor geolocation.
The generated image URL can be used in your website or any HTML image source tag.
Your can dynamically change images depending on visitor country, state/region, city, latitude-longitude-radius zone and IP address.
You can create multiple image location rules, with each rule having its own image and locations. Let us know if you have any questions about this!
