PostyBirb has been a lifesaver!

It can upload to inkbunny and HF too! So at least it can help with that, lol.
Good luck with your posting :>

it saved my life when I had to post a backlog of like 400 pieces >_>

Oh yea, I plan to use it for Inkbunny but I'm way more behind uploading to IB than I am to FA (And even more so to HF @_@)

Plus there's image dimensions I have to keep in mind with HF (no bigger than 1500 on the longest side) and I generally resize things to half their res to IB since IB gives full res stuff. REGARDLESS yea lol. Just a lot of work

I just finally tried it myself! I REALLY like how you can queue stuff up for uploading at a proper time and you don't have to remember and sit there and input every little detail....

Posty Birb is pretty useful once you figure out it's quirks! The creator is very responsive on their discord, if you have any issues. I use it to upload for a couple artists i know
