Thread-topic: Problem reading in large textures in GeoTIFF format on Apple Mac Book Pro 17" and VTK OpenGL libraries
Yes but image data will need to be copied anyway, so for best memory usage I would drop the original image data once the textures are ready.

Yes, that's your best bet, and by using of the pixel unpack settings
you can cut sections out of your image when you create the textures.
(GL_UNPACK_ROW_LENGTH, GL_UNPACK_SKIP_*, etc)
Saves you building data buffers where the image data is continuous.
