Yes, as imccasey says you can safely do 3-5 accounts (I typically do upto 3...but have done upto 5 without issues). You are definitely better using the same IP for posting etc as you used to create the account. You can change the IP, but don't do that often...maybe one or twice if you need to. So, if you have rotating proxies...don't use them unless you can 'sticky' the IP. My experience of using rotating proxies i.e. ones that change every session or so many seconds has resulted in higher (like almost 100%) suspensions/shadow bans.
Can you talk about what software you are using to publish picturesYou can create ~3-5 accounts/IP. If you get residential proxies with rotating IPs, this number jumps to ~15-20 accounts. Better to access the accounts with the same IP, you could get blocked otherwise.
