All transparent pixels will show a cherboard backdrop instead. If it suits you, pay $10 Lindens and upload the texture. Once uploaded the texture's transparency will not show up, but that's okay. It's just an SL "feature." As long as your transparency shows up in the preview, it will appear when you apply it in world.
