Thanks that did uncover an error but i am not sure that it is related. The error that i get is a Heap overflow: [EMAIL PROTECTED] shp2img -m stereo.map stereo.png *** glibc detected *** shp2img: free(): invalid next size (fast): 0x09161008 *** ======= Backtrace: ========= /lib/i686/nosegneg/libc.so.6[0x3ba2c8d] /lib/i686/nosegneg/libc.so.6(cfree+0x90)[0x3ba6340] shp2img[0x80a985e] shp2img[0x805ae2e] shp2img[0x805e6b5] shp2img(main+0xd1)[0x8050071] /lib/i686/nosegneg/libc.so.6(__libc_start_main+0xdc)[0x3b51f2c] shp2img[0x804ff11] ======= Memory map: ======== 00101000-00113000 r-xp 00000000 08:01 6662305 /usr/lib/libodbcinst.so.1.0.0 00113000-00114000 rw-p 00011000 08:01 6662305 /usr/lib/libodbcinst.so.1.0.0 00114000-0011c000 r-xp 00000000 08:01 6655932 /usr/lib/libgrass_dbmiclient.so.6.2.2 ...... ...... But even when i correct my mapfile so that an image displays on the web page, i still get the error above when using shp2img even though my page display correctly.
