Zinchenko has the idea that by using .svg files from Inkscape it should be possible to make them language agnostic, so that translators could simply add applicable texts to the image. I have no idea whether this would work, or even whether it would be less work than creating a new screenshot. Would you mind talking to him about this? Thanks.
(By the way - have you noticed that it is now possible to translate the page title within the normal translation system?)
