Ayman,

I just saw your fltinfo.txt and would like to add my 2c to your thread:
For both of the images, you are using a datatype of 32 bit floating point. It 
is very well possible that not all viewers can show a 3 band 32bit float 
tiff? Maybe you could try to save it with outputtype byte. You won't need 
32bit floating point anyway, if your data came from 256 color bmp... Saving 
as byte would save you a lot of disk/memory space (and reading speed). You 
could also try to save it as a 8 bit palette image, but I am not shure 
whether gdal_translate can produce such a tiff file...

Vincent Schut.
