I get around 21 rows and each row has approximately 6 columns.
The difference between text results and image results, is usually that in a text search, you usually find what you are looking for in the first few results (usually on the first page).
On an image search instead, the result you are looking for is more open to what you imagine to find in your brain.
So you might have to see several dozens of images to find the one that you have in mind.
That is why usually search engines like Google or DuckDuckGo offer endless scrolling. Even though after some endless scrolling, the images might not be as relevant as the first results, they might end up being the image you are looking for.
