If I understand correctly, you want to use one image when the phone is in English, and the other when the phone is in Russian. You should use the language modifiers on the drawable folder, not in the drawable name.
So, you would have a folder named drawable-en, which would contain your image for English (drawable-en/image.png, for example). Then, have another folder named drawable-ru which contains your Russian version of the image, but it must have the same name (drawable-ru/image.png).
Then, in your layout XML (or wherever you're referencing the drawable) just reference @drawable/image ... Android will automatically choose the appropriate image.
