MantasBeloglavka JillDiefenderfer hmm I disagree. I would avoid google images altogether, you can get into all sorts of DMCA and copyright issues there if you're not careful, see one example: https://petapixel.com/2017/10/19/yes-using-copyright-photo-without-permission-can-get-sued/
And as someone who had an artist come after me with copyright infringement complaint because I put a product in my store from Aliexpress where the supplier had used her painting on their products (I had no idea though this was someone else's work but common in China obviously - it was a tiny! image) and she sent me a take down notice, it was all legit and she was genuine after some research. So it happened even to me after only using AE for 3 months.
Most Aliexpress suppliers are usually fine with you using their images but I've had one only last week tell me that I couldn't use their images without the watermark unless I bought something first. I instead decided not to go with them as a supplier because they weren't as helpful nor very friendly in their approach like others I've worked with for a year now and my good suppliers were helpful right from the get go in ways like that when asking for images etc - so asking for permission although a bit of hassle, is also a good way to test how helpful they'll be with you, their communication and how willing to help you down the road they'll be. If they're like that in the beginning (demanding a payment rather than just trying to build trust, be friendly and hopeful for a potential partnership with you if you're clear that's what it'll be if they allow you to use their images - then move on to someone else who will don't waste time with them) you then know how helpful or not they'll likely be when you have real problems with orders and things etc.
