Custom Maker

Somebody know how change icon marker? I wish put my own image on each   store

Hello,

It is not possible out of the box. If you want to have different markers for different shops this will require a lot of modifications.

If you want to change the default marker for all shops it will be easier. In the Google Maps documentation, you will find out more information: https://developers.google.com/maps/documentation/javascript/custom-markers
