Well...
If you look at the size of your output file, the size is quite huge... ^^
12345 x 23456 pixels, that's quite a big image !! ;)
Here is the result of gdalinfo on the image :
Driver: PNG/Portable Network Graphics
Files: f:\temp\4947ac7e_29f5_0.png
Size is 12345, 23456
Coordinate System is `'
Corner Coordinates:
Upper Left ( 0.0, 0.0)
Lower Left ( 0.0,23456.0)
Upper Right (12345.0, 0.0)
Lower Right (12345.0,23456.0)
Center ( 6172.5,11728.0)
Band 1 Block=12345x1 Type=Byte, ColorInterp=Palette
Color Table (RGB with 256 entries)
0: 255,255,255,255
1: 0,0,0,255
2: 255,0,0,255
3: 234,233,233,255
4: 233,232,233,255
5: 234,233,234,255
6: 233,233,233,255
7: 215,148,53,255
...
Now, you should look at your map file to see why this output size :
IMAGETYPE png
#NAME "mapa"
SIZE 12345 23456#583 421
So, you put 12345 23456 as the optimal size for rendering the whole map and you
commented another size (583 421).
You should try to put the size of your input file instead of 12345 23456.
Something else is coming to my mind ? Why do you want to use Mapserver to serve
a file like this one ? Couldn't you use your web server to serve it ?
