Thanks again @dimmqb for checking. Yeah, the tour section of hivebuzz is really good for me as a noob because it gives me an idea of some of the things to pay attention to.

As for the images, yep I can only link to the free versions of them on pngtree. You can only get the unbranded licensed versions once you're logged in which I can't link to. But as I mention, I have a lifetime license to pngtree so any images I use are covered by that license. To be honest the license lets me use the images as my own so I don't actually need to attribute them at all, but I'm happy to give credit to the artists.
