Hi Catalin,
I created romanian variants banner (based on Nicu's comment).
You see it here -

Once I had a script in python that add text to images.
Maybe if it was useful.
For future releases could be considered a great automate the creation of
banners (now I have created over 1200 png files for more than 30 languages).
Thanks,
Alexander.
