Source your content correctly or make your own. What seems like a very well researched story is gone because of lazy understanding of rights.
Just republish without the images, it's not a difficult SEO space to rank in, 301 the old article, contact anyone you can to replace the backlink to your new url.
Most SEO content is garbage, rehashed, outdated, unproven.
I have the benefit of owning over 300 sites and managing another 300 or so in some capacity including full analytics access. I don't often see content written by people who "do" and work across diverse industries.
But if you define where you are starting I'd be happy to send a few ideas your way.
Is there anything you'd suggest to get started writing? I was looking to build an audience before starting a software project.
Thanks
