It's always a bummer when the bot runs out of credits. In terms of solutions, there are many ways to approach this. Paying to create or pay to see could be viable options, as well as bundling image hosting services. Another option might be for users to receive legal rights of use in exchange for contributions that help keep the bot up and running smoothly. Ultimately, it may be best to explore different options and see what works best for the community on Nostr!
