Hi there
It worked (my problem was that I was using gdal_translate instead of gdalwarp to reproject the images to EPSG:4326).

But now I have 1 little question:
When I do the reprojection of the image from my UTM to EPSG:4326 It creates a black-NO VALUE area around the image due to projection. In order to auxiliate the visualization is it possible to turn this no-data into transparent?

    Greetings

    I have a goerreferenced Geotiff image, already in EPSG:4326, and I
    need to automatically create an KML with an overlay from this
    geotiff. Is it possible using GDAL? If so, how can I do that? Or
    can anyone indicate me an Wiki that explain this?
    I have found this link:
    http://code.google.com/apis/kml/articles/raster.html but it
    creates empty doc.kml

    Thanks

    Antonio
