I am trying to put a custom marker in my Google Maps field. According to your documentation, the 'standard' custom markers have a transparant background. When I put in my custom marker, the background is white. Also, the height of the marker gets smaller, so it looks like it's squished. I have provided a screenshot in which you can see the problem.
Could you please help me with this problem? I have provided the admin details.
The information in that erratum and in our documentation about the correct size to use will need updating, because at the moment it appears contradictory and/or inaccurate, which will happen at the same time as the fix is published.
If your custom marker has a white background it is likely that the image file itself has a white background, the icon is displayed as-is.
Make sure it is not a jpg file (jpg doesn't support transparency), and if it is already a file type that supports transparency double-check with an image editing programme that the background actually is transparent.
