如何在 Google 地图 JavaScript 中说:“我想在这个纬度和经度上放置一个标记,带有动画,以及这个 30x20 的图标 [带有图标所需的任何信息]?”
我可以拥有多少个不同的图标有任何限制吗?

我认为您正在寻找这个:Google Maps API - Overlays
那里有一些非常好的例子......
通常有一个用于覆盖的图标和一个用于阴影的图标,但您可以覆盖此行为...
编辑:添加了更多内容:
没有默认阴影。如果您使用自定义图标,则需要为阴影提供图标和图像。我过去曾使用自定义标记生成器来生成阴影图像。
这是来自 Google 的一些示例代码。注意图像和阴影都被指定了......
