Hi folks, I occasionally get emails from users about PBGrab, and PB2Smug two scripts I had written a few years ago to download data from PBase galleries.
I no longer use PBase and don't support any of the tools.
So anyway, it seems another PBase user adapted it and converted it into a perl script which has the advantage of working on OSX/Linux/Windows - basically any environment that can support Perl being installed. It will require you to install perl and stuff, but given he last updated in in 2016, he may be willing to answer questions. I don't know. But if you want, feel free to star his efforts on GitHub and ask him questions via Github issues.
His repo is here: https://github.com/RichardMN/pbgrab
Thanks
