For reasons I won't get into, I have a set of TMS-format directories which provide tiles to a few OpenLayers maps I maintain. These maps are required to only allow zoom levels 6-12 to be accessible. Currently I have done this by creating a new directory with symlinks (i.e. 0 -> 6, 1 -> 7) and setting numZoomLevels in the OpenLayers.Map object.

I figure there's got to be a better way to do this. When googling for others with this problem, all I found were suggestions that were layer-specific (minZoomLevel or something), or sounded WMS-specific (adjusting resolutions array).

Any help would be very much appreciated. Thanks in advance.
