signature image cache

Ciao to all.

I have a customer with 15 user and they have an HTML signature with pictures included into the code of their Apple Mail.

Images are stored into a server exposed on internet.

Just To be flexible, I'm use to change the picture linked into the signature on the server; So i can change the picture into ALL signature.

BUT Apple Mail decided to NOT refresh the image.

SO there is something cached into the local cache folder who prevent to reload/refresh the image.

Someone has a suggestion for me?

Thanks / Grazie / Merci / Danke
