How did Google images normalize the width of each row?

It's easy to resize images so that they all have the same height while maintaining the aspect ratio, but how did they fit them all on a row such that every 开发者_如何转开发row has the same width? Did they crop some of the images or what?

Remember in google images (apart from cropping) -

1. Spacing between images are not always exactly same.
2. Height of all images in a row are also not always same.

Using above 2 techniques i.e. tweaking the spaces between images and changing size of image little bit by compromising height you can achieve this. In fact the the justify paragraph option in the text editor also use the spacing technique. They evenly distribute the extra spacing between all word.

You don't always get a good spacing in google image search. See this -

they actually figure it out through an algorithm to put images next to eachother so with the padding and everything they end up being the same width then they cache that page for the keyword you searched for!

I found a very interesting article while looking for the same thing. If you look at google images you can see not all of the rows have the same height. but all the images in a row have the same height. So what you want to do is calculate the right height you need for the row so the images will fit (the images stretch if they get higher or lower). This article will possible help
