Effective gadgets for side visibility?

Received my set of leduswheelus lights today (ordered last week) - packaging with my name printed on it, a short letter, devices and zip ties inside. Most surprising was that handwritten paper letter :) First impressions: devices look great, weight almost nothing - so overall I'm happy.

Can anyone tell how to create an image library? I've saved an image, but where's a button for a new library?

you need to sign in using a twitter account (openauth or whatever it is) to create libraries.

then you download the library and install it to the device using the software for mac/windows.

mine arrived today, very impressed by service and packaging but sadly one of the led's has got a dud red emitter so just sent an email to see what my options are.
