The Nasa images are available here: http://visibleearth.nasa.gov/view.php?id=74218. The problem I am having is that the images come into Qgis without the proper geographic coordinates. The Nasa documentation says that the images are in the Plate Carree projection and the projection datum is WGS84. But with my very limited knowledge of map projections I do not know how to set this up in Qgis so that the images will be positioned properly and use decimal degrees as their units. Any help would be greatly appreciated.

EPSG:4326 WGS 84 is the projection to pick when loading the data.
If you happen to download all of them you can also make a GDAL VRT to
load everything as if it's one layer.
Enjoy,
