How do I send photos from my iphone to my new HP laptop via bluetooth?

You don't. This has never been a feature of the iphone.

You don't, as such is not supported. This is how you do so:

You don't. You use a cable to transfer photos, the same way you would with any digital camera.

不允许这样做的，APPLE产品的数码产品中的蓝牙只用于上网数据切换和外拓展功能的！
