If you want to be extra safe, you may use the collection that contain the md5 hash of the images from a download in may 2022.
In that case you can use --compute_hash "md5" --verify_hash '["md5","md5"]' to automatically drop out the images that do not match theses hashes.
As of january 2023, that means dropping about 15% of the dataset. Some of those images are actually still good but have been slightly changed by the websites.

If instead of saving to a local folder you prefer saving on eg aws, you may use commands like this:

You may also decide to put a & at the end of the line to download all files in parallel. (in this case expand the for loop in multiple lines for bash syntax reasons)
This one is big so I advise doing it in distributed mode. I followed distributed_img2dataset_tutorial.md. Note some aws specifics in that guide (in particular regarding VPC and security group configs to allow worker and master to talk together) Below is some specifics.
In practice I advise to rent 1 master node and 10 worker nodes with the instance type c6i.4xlarge (16 intel cores). That makes it possible to download laion5B in a week.
Each instance downloads at around 1000 sample/s. The below config produces a dataset of size 220TB. You can choose to resize to 256 instead to get a 50TB dataset.
Example of master config:
./spark-3.2.0-bin-hadoop3.2/sbin/start-master.sh -p 7077
Example of worker config:
parallel-ssh -l $USER -i -h ips.txt './spark-3.2.0-bin-hadoop3.2/sbin/start-worker.sh -c 16 -m 24G "spark://172.31.46.59:7077"'
