Can any of the Garmin watches with IQ Connect display an image? For example, could I load a picture of a person's face from a URL on the Forerunner 235? And it not look like a mess?
makeImageRequest is supported by the SDK, but the Communications module is not allowed in watch faces, so they cannot make these requests.
You can build images into a watch face and display them on the device.
The screen technology used on our wearable devices supports 64 colors. Some devices are limited to 16 colors (white/grey/black + most primary colors) due to memory constraints. For devices that support the full 64 color palette, most images look decent when dithered, but there will definitely be quality loss when compared to a computer screen that supports 16-32 million colors. On devices that are limited to 16 colors, images may need to be more carefully selected to match the colors that are available.
