I've set up image boards before. Vichan is very easy for multi-board, fully featured stuff. If you only want a single board or not many features then TinyIB is probably the best. I used a Vultr VPS for my image board, fairly cheap. I'll help if you like.
Thank you! I would love to have you for future development of if a new dev spot opens. So far we are pretty much ready.
Let me have your discord possibly if you are still interested ;) our website is venuschan.pw
