Hi,
>From your gdalinfo output:
Upper Left ( 0.000, 1300000.000)
Lower Left ( 0.0000000, 0.0000000)
Upper Right ( 700000.000, 1300000.000)
Lower Right ( 700000.000, 0.000)
Center ( 350000.000, 650000.000)
So the extent in the map file would be:
EXTENT 0 0 700000, 1300000
Then your TIFF should appear in the output of shp2img.
However, these do not seem to be geographical units. Anyway, it does
match the extent of your layers seen in your first message.
I think your .tab file is not taken into account.
Try with a world file (.tfw) which is more "standard", or better, make
it a GeoTIFF (use GDAL tools for that).
