Permalinks of images with duplicit names

Hi,
great plugin, by the way.
It would by great if you improve behavior of permalinks of images with duplicit names for users who use your prefix feature.

I have your prefix feature set to “image-“.
I create post “My Post” – it has slug “my-post” and url http://www.domain.com/my-post/
I upload image “my-post.jpg” – it has slug “image-my-post-2” and url http://www.domain.com/image-my-post-2/
I upload duplicit image “my-post.jpg” – it is renamed to “my-post-1.jpg” and it has slug “image-my-post-2-2” and url http://www.domain.com/image-my-post-2-2/
I upload another duplicit image “my-post.jpg” – it is renamed to “my-post-2.jpg” and it and it has slug “image-my-post-2-3” and url http://www.domain.com/image-my-post-2-3/

The best scenario is:
Image “my-post.jpg” – slug “image-my-post”
Image “my-post-1.jpg” – slug “image-my-post-1”
Image “my-post-2.jpg” – slug “image-my-post-2”

The good scenario is:
Image “my-post.jpg” – slug “image-my-post”
Image “my-post-1.jpg” – slug “image-my-post-2”
Image “my-post-2.jpg” – slug “image-my-post-3”

Please consider this small feature 🙂
