Blank image being created in MS 4.6.0

[Mike Boos]

Hello

I'm trying to upgrade our map server from version 4.1 to 4.6.0 and am 
facing some hurdles. The map files work fine in version 4.1, but are all 
generating blank white images for me in 4.6.0. From reading the mailing 
lists and the documentation, I can't seem to find what's wrong with the 
map files. Here's an example:

#epsg:32611
NAME AUG21234542.map
SIZE 400 400
EXTENT 0 0 576 432
WEB
TEMPLATE ../mapServerTemplateVis.html
IMAGEPATH ""
IMAGEURL ""
END
LAYER
TYPE RASTER
STATUS DEFAULT
DATA "C:\inetpub\ftproot\input_images\AUG162454635.jpg"
PROJECTION
"init=epsg:32611"
END
TRANSPARENCY 100
END
END

Does anyone know what changes I need to make to have the image appear on 
my map?

Thanks
