When using the 21600 x 10800 JPEG image found here: http://visibleearth.nasa.gov/view_detail.php?id=8391 (after being converted to a .tif using irfanview, smaller images using the same conversion settings worked fine) teqser throws up the following error:

    Appears to work fine on MacOSX and Linux machines, must be a Windows issue.

    This is very likely because aqsis_tex isn't memory efficient when downsampling: it simply reads the entire image into memory before doing any operations. Fixing this problem is probably a task for after the OIIO texture library integration. (OIIO may even have memory efficient downsampling already in which case we won't need to do anything!)
