The raster files are in jpg format. They are a set of 3 tiles NOT
GEOREFERENCED (of course, they are jpg!). But, i have a shapefile,
called tile.shp (so, georeferenced) representing the footprints of the
tiles. In tile.shp, I created a field (Path) including the absoulte
path to tiff tiles on my disk (ex. /var/www/.....F4-C4.tif).Now, i
converted the jpg files in tiff files, without the world files. I use
this mapfile configuration:<br>
<br>
LAYER<br>
NAME "pannelli"<br>
STATUS ON<br>
TYPE RASTER<br>
TILEINDEX "./tile.shp"<br>
TILEITEM "Path"<br>
END<br>
<br>
I run maplab, but an error occurs: unable to open tiff files:<br>
<br>
<table border="0" cellspacing="0" cellpadding="2">
<tbody>
<tr>
<td colspan="2"><font face="Arial,Helvetica,sans-serif" size="2"
color="#000000">Description</font></td>
</tr>
<tr>
<td colspan="2"><font face="ARIAL,Helvetica,sans-serif" size="2"
color="#ff3333">Unable to open world file for reading. in
/maplab/htdocs/common/wrapper/drawmap.php</font></td>
</tr>
<tr>
<td colspan="2"><font face="ARIAL,Helvetica,sans-serif" size="2"
color="#ff3333">Failed to draw layer named 'pannelli'. in
/maplab/htdocs/common/wrapper/drawmap.php</font></td>
</tr>
<tr>
<td colspan="2"><font face="ARIAL,Helvetica,sans-serif" size="2"
color="#ff3333">Unable to open world file for reading. in

</tr>

color="#ff3333">Failed to draw layer named 'pannelli'. in
/maplab/htdocs/common/wrapper/drawmap.php</font></td>
</tr>
</tbody>
</table>
<br>
So, i created some empty world files! This time, maplab runs without
error, but it doesn't show me the tiles. It shows me only a blank page.<br>
Where is the problem?<br>

files? Right?
thanks

Yes, as long as the georeference information is there for the tile
index to be created (and for the image to be rendered properly).
GeoTIFFs can be used in a TILEINDEX layer without world files.
