Hi Ben, we have a 25MB limit for nostr.build free uploads. You could probably compress it, or like nostr:npub1jk9h2jsa8hjmtm9qlcca942473gnyhuynz5rmgve0dlu6hpeazxqc3lqz7 mentioned, no filesize limit with an account. We also just implemented nip98 for Amethyst, meaning the account is integrated to your uploads.
