edited image not being saved and displayed properly

[Fawcett, David]

Usually this issue is due to the EXTENT or PROJECTION settings.  It
sounds like you are really getting a new image with every request, it is
just not showing any data.  

Make sure that your own data falls within the bounding box defined by
the EXTENT at the top of the mapfile.  The extent is defined in the
units of your spatial reference system.  For UTM this is meters, for
lat/long it is decimal degrees, etc.

Also, make sure that the value for UNITS is set to the proper units for
your spatial reference system.  

Another thing to check is to see that your layer has a STATUS of
DEFAULT, or you are adding the layer name to the post or get request
(e.g. &layer=myNewLayer)

If this doesn't help, I suggest posting the text from your map file.

David.

i have got a bit success in going through the interactive html page. i 
have used exampe1-9 of the tutorial, which is working fine, but as 
soon as i change the map file to my own data, then i get the full image 
only once i.e. at the time of first load. as soon as i click the image
at 
any location, i get a blank image, and that is what is saved in the tmp 
directory, a blank image.

why my new image is not being saved and displayed, can anyone 
please help.
thanks.
