You can create language versions of the text in EPi-server, but I haven't found a possibility to create language versions of images.
If you are working with marketing you might want to show a different image in Russia and the US. E.g. I used to americanise images for Wayfinder in the US just to take away the impression of having a Swedish company as the sender.
You can do this by storing image paths in the languagefiles.
I'm not sure I follow...
If it's an image in a property then it's a matter of making a globalized version of that property...
I might be way off here, and totally missunderstaning what you are trying to achieve.
