Looking for a mass image downloader

I want to grow my Instagram using other photos that are royalty free and have a lot downloaded and ready to go to use but the problem is, every application I have tried to use either wasn't compatible with my windows 10 or wouldn't work because maybe i was using it wrong?

Can I have a suggestion please?
I can't seem to find anything that works and I don't know how to make my own programs yet (although I'm planning on learning python and such).
