Hi.  I have a map that is broken up into a bunch of .gif tiles.  I want to 
display them on a layer in Mapserver.  I have working version of what I want to 
accomplish, but it uses one .gif (the big map pic), attaches the big map to the 
globe via a world file.  That big map .gif had no georeferencing info attached 
to it.

These .gifs have no georeferencing information included or attached as well.

I read Section 4 (and Section 9 too) on the mapserver site page: 
http://mapserver.gis.umn.edu/docs/howto/raster_data

>From this I learned that I need a tile index shapefile.  I noticed the snippet 
>at the bottom of Section 4 about gdaltindex and creating a tile index 
>shapefile.  I tried that.  

Here's what I typed: gdaltindex u_of_ill.shp ~/Desktop/UofImapSquares/*.gif

Here's what was returned to me:
It appears no georeferencing is available for
`/home/jimbo/Desktop/UofImapSquares/A0.gif', skipping.
It appears no georeferencing is available for
`/home/jimbo/Desktop/UofImapSquares/A12.gif', skipping.
and so on.........

Ok.  Yes.  I know.  There's no georeferencing info attached.
But, how do I go about attaching georeferencing info?  
And how do I create, edit, and view a shapefile?
And lastly, do I need a world file to determine a global position for every 
tile?

I tried using a text editor Gedit (I figured What the Hey?) to open them and 
nope - wasn't in UTF-8 encoding.

I did some digging Google and noticed that you can use ArcView GIS, ArcMap, 
ArcGIS, and ArcCatalog to create, edit, and view shapefiles.

I also stumbled across posting that talked about ShapeLib created by Eduardo 
Patto Kanegae and maintained by Frank Warmerdam.

I don't have money to spend on buying some GIS program, and ShapeLib seems like 
the answer.

Could anyone help?
