Here is the official explanation of what the Activity is looking for – builders should share their builds on the very same page it is published:
The toy photography community BrickCentral ran an indoor photography contest in June, can you impress us like they did? Shoot some minifigures pictures inside your home with common household items.
This is part of a series on LEGO Ideas that gives little tasks for builders to get involved with – there are no prizes, they are just a way to get involved with building something quick for fun. Each challenge is intended to be something quick and fun, unlike the more in-depth building required for a competition or product idea.
The deadline for this Activity is July 21 at 10.00am CEST.
