go to Google and then Images, enter "Thai Cuisine" in the search field, lots of images. Right click on any chosen image and choose "Save As"
That is fine, as long as you fully understand what you are looking for. Otherwise you may end up in a right stew. Probably Irish. LOL
I do the same kind of search for images, but avoid Google. I use Duck Duck Go as they do not track you or mine your data for nefarious and commercial purposes.
Actually, it doesn't really matter. VPN's are also fairly useless. Fact is, you cannot hide your Traffic from your Internet Provider. The people who supply you with a connection can monitor EVERYTHING about the connection. If your activity COULD be hidden, they wouldn't be able to track usage and wouldn't be able to provide you with a comprehensive bill at the end of the month, not wold they be able to know if you were experiencing an outage while others retained their service. Add that to the fact that if a Law Enforcement Agency demands to see all of your traffic, the Provider must comply with a legal summons or Subpoena.
I recently found a site with pad thai images and here you can download these photos and use them. I always download here when I'm working on different projects. It’s very convenient, and most importantly, it’s high quality. It is very important for me. Because I work as a designer.
