Raccoons aren't native to the UK (or Australia) so it's less likely that people would even know what the picture represented, let alone understand that a word which is almost exclusively a racial slur in the UK is a short form of the name of this strange animal in the picture.What, do they need an arrow between 'coon' and the image of the racoon?
Why would it be a clarifying image, given that the majority of people probably wouldn't recognise the animal, and even if they did then the shortened form has never meant the animal here?For some reason you have introduced the idea that they would see the clarifying image as obfuscating instead. I see no reason to assume this would be true.
We've heard of the animal, some people might recognise it from a picture but there is simply no association here with the short form and the name of the animal.
You can't ignore the cultural references of the country in which you are trying to sell this hypothetical raccoon cheese - and a product called raccoon cheese would be assumed to be made of raccoon milk anyway, in the same manner as goat cheese.
