Welcome to Hive my friend!
Happy to see someone is already being helpful, and suggesting pictures and the introduceyourself post. Definitely make sure you got your profile setup, and make a good first impression with that post, and lots of ppl follow that tag to help out new members.
Then find communities with similar interests, comment on a few of their posts, then begin posting, while also releasing a trickle of your old content to catch them up to speed, and allowing you to monetize previous work. Just don’t blow your load of good content all at once, as you want to really network, and grow your following first.
Thanks for the advice, I'll do all that :)
