Randomizing Images for watch face

[Deftwist]

I want to create a watch face that displays the basic information such as time, date, steps, battery and cardio with a image in the center that changes to different images. Hopefully I could set it up to change the images to each time the watch wakes, or change with the date and time.

I'm hoping someone can point me in the right direction for code so I can create the watch face that I really want.

I've done a few things like this. To change an image, change the .href of the <image> element's object in .js.

I've made one with 12 pics (one each hour), but it takes forever to install it. (Because the pict take a lot of time to download over bluetooth). So you better take a look at an example that takes a picture from the internet. And take some time between them. 

Time between wake-ups might be to short.
