Ezequias -

Be sure to be VERY careful about paths, even in email!  You said you moved the image to the folder "/raster" - did you mean to "/var/www/cgi-bin/raster"?  That would make sense.

And I would agree that if that is what is happening, it is probably a permissions problem on the directory and/or file.  The cgi-bin folder is probably not a good place to store your raster data, as it may be accessible to HTTP clients.  Most users put their data in a local folder that is accessible to the mapserv CGI program when it is running, but which is NOT accessible via an HTTP request to the Web server.

Ed,

It is working now, but let me say what occours:

1- I have the image on the cgi-bin folder
2- My map file is: 
        shapepath "/var/www/cgi-bin/"
        LAYER
        NAME "Imagem23"
        data "recorte_23.tif"
        STATUS default
        TYPE RASTER
        PROCESSING "DITHER=YES"
        PROCESSING "BANDS=1,2,3"
        END
3 - The error reported when I try to load on the Browser is:

        msDrawMap(): Image handling error. Failed to draw layer named Imagem23'. 
        msDrawRaster(): Unable to access file. (recorte_23.tif) 

4 - a) I copy the image to the folder /raster 
      b) Change the LAYER parameter to:
      data "raster/recorte_23.tif"

 5- The image appears on browser

If I didn't make the step 4a the message on step 3 will be repeated.

Does it make any sense ?

Sincerely
Ezequias

Ezequias -

OK - you will want to get to a TILEINDEX, I think, if your layers are simply separate images that all belong together as a single set of one type of image.

But you don't need to worry about that now. Just make sure the DATA statement in each LAYER specifies the full pathname.

I suggest you try to get ONE image working properly first, then get the other 115 working. Did you have one working at all?

Ezequias -

Please always reply to the whole list, so everyone can help - thanks!

MapServer may be strange but it should be consistent. Do you have a TILEINDEX for these 116 images or are they each specified in a separate LAYER in your map file? It doesn't matter where the images are (if the permissions are OK) but you should start by putting the full path to each image in either the map file LAYER block or in the TILEINDEX shapefile.

Ed,

Mapsever works strange. Some file works on the cgi-bin folder others on cgi-bin/raster.

I am working with 116 images too. I don't know if it makes any difference.

Sincerely
Ezequias

Ezequias -

This is probably due to the paths to the data. Your error message reports a relative path, which depends on the "current directory" on your server. It is easier to always use full pathnames (starting with a "/") to your data files when you're getting started. Try putting the whole path in your map file to see if that solves the problem.
