To increase the security against hackers, you can compare the checksum of the Zip file you download against a list of checksums generated before the images were uploaded.
The list of checksums for the GoldenOrb 2020-03-01 release can be found at this Github site. These are SHA256 checksums.
Windows users can download QuickHash-GUI to generate the checksum on the Zip file you download and compare that against the checksum value from the Github site. Remember to select the SHA256 hash for the image. This program is portable and does not need to be installed to work.
