i am using ARB_texture_compression and EXT_texture_compression_s3tc...and then i pass GL_COMPRESSED_RGBA_S3TC_DXT1_EXT to my glTexImage2D()...this means i''m creating an s3tc compressed image and sending it to my video card ram right? after sending it to vram, it want to save it to file and load it again in the future through glCompressedTexImage2DARB() stated at: http://oss.sgi.com/projects/ogl-sample/registry/ARB/texture_compression.txt problem is, how do i save it? thanks.

There''s a step by step explanation in the link you posted to save the compressed data. See issue 10.
