The face is too big. It needs to be 256x256
It can be any power of 2 (256, 512, 1024, 2048, 4096...). The thumbnail just needs to be 64x64.
I found 3 things wrong:
1. The file name contains ".zip" twice - it should only be there once.
2. The face itself is 600-something square. It needs to be a power of two, as I mentioned. You should probably scale it down to 512x512.
3. The thumbnail is too small, it's 60x60 and it needs to be 64x64. Scale it up.
