As you may think this may not be a long term solution as perhaps die.net may block curl also. I haven't heard back from them yet. If possible I'm going to try to work with them and try to find a solution.
I mention on the last post also that I'm looking at other long term solution like using an external server to download the maps to, and RSW to point at those images instead but all this will take a bit more time.
Thank's again for your feedback and support
