Problem with galaxy texture

[poyzone]

Hi,
Excuse me but i'm french and my english is not prefect
So, my problem:
I install the M31 galaxy into de extras folder (just unzip into this folder).
My Celestia version is 1.3.2, and i'm under linux (mandrake 10.1).
When i start Celestia, i select the M31 galaxy --> go to:
So i can see the galaxie, i can turn uround her (3d effect is ok), but the galaxie is just white ! no texture !
It's the same with over galaxie like M33, M109, ...

Someone can help me?
Thanks

my config: Athlon XP2500 Barton, 512 Mo ram, video Geforce Fx 5500 128Mo, mandrake 10.1, celestia 1.3.2

As you are on linux, the most common reason might be that the addon-creator did not care about consistent naming of the texture. Many users are not aware of the fact that on operating systems other than Windows all filenames are case sensitive.
Compare the filename specified in the .ssc file that came with the addon with the actual texture file name. You may switch on some kind of logging console in Celestia (using key '~' if I remember correctly) to find out about errors loading the texture.
Another reason might be that the texture size is too big. There is a menu entry "OpenGL Info" somewhere in the (Help?) menu. There you can find about the maximum texture dimension your graphics card can handle. (This limit does not belong to spherical bodys like planets, as Celestia can split large texture images in these cases.)

Hope that helps

Thanks a lot steffens ! you're solution is ok !
The filename of the texture was not in the good case for linux. So, i change it from m31.png to M31.PNG (i can see it in hexedit, as you tell me), and now, i can see complet M31 with texture under Celestia !

Thanks !
