Need some suggestion about reading and displaying an image file

[The Little Body]

For to manipulate the image, alls informations you need are already used at the line that load the texture from the RAM to OpenGL ...

 
glTexImage2D(GL_TEXTURE_2D, 0, ilGetInteger(IL_IMAGE_BPP), ilGetInteger(IL_IMAGE_WIDTH), ilGetInteger(IL_IMAGE_HEIGHT),          0, ilGetInteger(IL_IMAGE_FORMAT), GL_UNSIGNED_BYTE, ilGetData()); /* Texture specification */

For to write it, use this DevIL functions :

ILboolean ilSaveImage(const char *FileName);

(you can found a .pdf file that explain how to use DevIL at http://openil.sourceforge.net/docs/DevIL%20Manual.pdf)
