Braille is a tactile experience, so replicating it any non-tactile medium is going to be imperfect. While I am not 100% sure why a GIF or PNG of the text would not suffice for sighted users, with appropriate alt text and even a longdesc as required, have you given any thought to something like sIFR? Again, while imperfect, it might give you a closer replication. To an extent, I suspect the issue is also further compounded by the fact that the Braille is probably not English (per se).

Sometimes we simply must accept that a visual representation, or in this case actually a tactile representation, cannot be carried over to one or more of the other senses. > > Any hints and tips for how to tackle this would be appreciated. Well, may sIFR as suggested above for visual output, but it will still leave screen readers (and, in a bizarre twist, users of Braille tactile output devices) shut out. Explain it the best you can in clear language.
