It's not entirely accurate, but it's good enough. Within a few hours you can have a pretty large dataset of whatever you want, really. (Yay for massive dataset plus user tags.)
You can snag a copy from my server, if you want. (Warning: It's a direct link to a 54GB json file.) https://battle.shawwn.com/sdc/f100m/yfcc100m_dataset.json
I have a script called "janky-image-search" that returns random results from searching this dataset. Here are a few random hits for `janky-image-search ceiling`:

etc.
The quality is hit or miss, but it seems better than 70%.
EDIT: Here's a gallery of the first 100 hits for "ceiling": https://cdn.gather.town/storage.googleapis.com/gather-town.a...
But as you can see, it's not effortless. Most of those ceilings are old. So it depends what you want. It's why labeled data is worth billions of dollars (scale.ai et al).
