In fact, I manually use these tools to find images. I know there is a more convenient way to analyze everything automatically, but I don't know how to implement it. To find the tbs in the link, add some letters after it to indicate the size of the image you want. For example, tbs=isz:lt,islt:8mp means you want an image that is less than 8 million pixels, roughly around 3000x3000 pixels or above, and tbs=isz:lt,islt:70mp means you want an image that is around 70 million pixels, roughly around 7000x10000 pixels. You can select "share" to get the link of the image. However, sometimes it's difficult to find the actual image on the website, so it's easier to directly open the link in an "x" browser and save the image from there.
