Hi all,

Am currently on my planning phase to use ESRI imagery services together with my imagery which will be in a map service and am trying to overlay it on top of the ESRI imagery service...have in mind I would like to cache my imagery. In which I will use ESRI scale levels...the doubt am having is will my cached image overlay on ESRI imagery services with out having any white areas around my imagery.....am thinking of running my cache on PNG format but I don't know how big that would be....if anyone may have any good ideas please help a brother out... :-) thanks.....
