Cannot change server icon in 1.7.2 development build

Hello guys, I have an issue with the latest development build bukkit. I am trying to chang the server icon. I made a little research before I post my problem here and I found that my picture has to have this name "server-icon.png" and also have 64 x64 dimensions. Ok so I put it in my bukkit folder and I restart my server and still it's like nothing changed Please help me.

 

hmm are you sure it's 64 x 64? It works fine for me

 

Well I tryied to serach google images and find a 64 x 64 image. I found one and I tryied with this image. Still no image was appearing. Today I grabbed the latest development bukkit build i tryied again with my old image and it worked Not sure why this happend..

 

Might have been a bug in that one dev build, they are development builds.

 

I use beta build 3 and my icon wouldn't load it says couldn't load server icon!!!! please help me
