Each language has its own directory where the transalted documention goes. 'C' being the default (English) language. In order to avoid useless weight it is a good idea to use the images in the C/images/ directory, that is using relative paths as "../C/images/image_name" and only use "images/image_name" (that is using an images/ directory under the specific language directory) for those images where a translation is useful (iamges whith text strings for exemple)
