    textures disappear when executable moved

    I have a glut application that loads 6 textures and displays them (although this isn't the only thing it does) when I copy the executable file (windows .exe file) and the texture files to a new computer they are no longer visible when the application runs. all of the files are in the same folder on both the development pc and test pc.

    please help.

    A sanity check is to try a simple 128x128 image, that should work everywhere.

    There is a good chance that one pc has a more capable hardware.
    Things to check, once GL in initialized, log some info :
    - maximum texture size :
    Code :
    GLint texSize;
    glGetIntegerv(GL_MAX_TEXTURE_SIZE, &texSize);
    - hardware support for non-power-of two textures :
    does glGetString(GL_EXTENSIONS) contain GL_ARB_texture_non_power_of_two ?
    - loaded image size. check it stays within the above limits.

    Do you use mipmaps ?
