I get an access denied when trying to view sandbox venue maps.  Ex:

tevo.configurations.show(2141).seating_chart.medium

=> http://media.sandbox.ticketevolution.com/configurations/static_maps/2141/medium.jpg?1308195220

If I remove "sandbox" from the URL it works, but this is a bit of a hack and I'm not always sure if the IDs will match up between sandbox and production.  Thanks.
