[Mapserver-users] have a dynamic map file?

[=?gb2312?q?Chen=20Fu?=]

Sorry, I didn't tell my story clearly enough.

I'm working in a Satellite Station of China. We
receive data of many remote sensing statellite like
LandSat, SPOT, radarsat. The total number of quick
view images will be enormous. and everyday we have
hundreds new quickview images uploaded to the web for
the people to browse. 

The user can pick out a perfect image from the images
overlaped on the same area according to the cloud
coverage or season. Sometimes the user would like to
have an image of a large area which compose of several
Landsat7 images. so candidate images should be listed
beside the mapsever's client and once the user click
on one of them, the new image is shown(or merged) with
the other images selected before.

My solution should be dynamic online. the image source
is updated everyday, so the static tiled layer
solution seems not feasible. 

Any other good idea? :)
