Hey guys,
I've posted here before but not recently. I run
https://siliconimage.irixnet.org which currently as of today runs Gallery3. I cleared this post sometime ago with Brad, so this is not an unsolicited ad but rather me sharing/offering a migration path.
I've been working with a dev I've known for a while on a new project that is kind of a hybrid of Gallery3 and a type of image board called a "booru". Our main difference from Boorus is the album structure of Gallery3 is retained, but we also have tagging systems and imagestreams that are used by Boorus.
The main difference is that we're targeting a legacy-free Laravel framework under an MIT license with eventual integration plans with mybb, as IRIXNetwork is first and foremost a retrocomputing forum.
Our main difference system-wise from Gallery3 is we're exclusively Postgres. It will be FOSS like Gallery3 and I'm going to share our migration tools as well. It'll take a lot of work to make it work for others, but I'll be offering help to anyone whose interested in migrating off. This is probably less of a "Gallery3" direct replacement and more of a spinoff/slide into a more public image submission system.
Be careful googling Boorus, BTW. Not all of the results that will come up will be SFW.
Let me know if anyone has suggestions or feedback.
