Yes you can. In order to use your own icons, you need to do the following:
- Load into your Joomla Root/components/com_gmaps/icons folder.
- Go to the GMaps control panel in the backend adminstration panels
- Select ‘Manage Icons’
- Select the icon name (this is retrieved from the filesystem)
- Specify the icon height and width
- Click ‘Save’
This was changed from the initial version due to a changes in the rendering class to ensure the icons would display.
