Say the name of the icon file is "special.png" and I put the same in the icon column.
After mass import, it is found that it is not taken.
So, I have to go to edit mode to enter the icon file name again and manually upload the image from my PC.
What is the correct way such that the above manual work can be skipped because there can be tens of thousands of places to handle?
1. save the icon file to bt_googlemap/place/icon first
2. then set the icon column in the mass import excel spreadsheet to bt_googlemap/palce/icon/special.png
