This is why I respect you. You're always looking to improve the situations you're in... And when you screw up, not only do you own it - you fix it.
It takes some courage to do that, and I applaud you.
As far as the images, when i search Google or Bing i filter for photos listed under creative commons free to share and use commercially. It takes away a lot of the results, but i feel comfortable using those without worrying I'm stealing someone's ability to make a living or anything of that sort.
good advice. paxabay has a lot of images too.
