Add language-specific images

To make Sphinx substitute the original images with language-specific ones, you need to use the specified filename format.

For example, to replace our easter egg image for English with those for Russian and Portuguese, we will use the default filename format {root}.{language}{ext}:

• Easter egg for English (the default image): egg.png

• Russian: egg.ru.png

• Portuguese: egg.pt_BR.png

Download the egg images for Russian and Portuguese and place them in the _static directory. Yes, that’s enough.
