Well size wont work - Google Maps alas always resizes to a fixed 32x32 px size. *
Colour should definitly work tho.
Can you provide a link to your map? A link to the Google Maps page is fine. if you cant share your original spreadsheet, perhaps a copy with a few sample placemarks.
* But can use that, by creating it as a 32x32 image, with transparent padding around it for smaller icons. |
