Best approach for localize images

Question

What is the best approach in order to localize images (buttons and other content) in a i18n rails app?

Answer 1

I usually inject the locale name in every path or in the image name. In the first case, create different folders for different locales

/public/images/en/file.png
/public/images/it/file.png

image_tag("#{I18n.locale}/file.png")

In the second case

/public/images/file.it.png
/public/images/file.en.png

image_tag("file.#{I18n.locale}.png")

I usually prefer the second solution because there are many assets I don't need to localize and I often need to keep translated/common assets in the same folders to take advantage of convenction-over-configuration pattern.
