Comparison chart 

Well, I was thinking of adding this picture to the article under "Non-human penises". But there seems to be much work behind having images on wikipedia. On the picture it says that it's allowed to be distributed freely, but considering how much legal jargong there is today I think it's better to have a more experienced member take a look at this before I upload it.

Here is the chart that compares human,dog and horse penises.

Please share your thoughts on the usefulness of this picture and if it's possibly to have it on wikipedia.
