Problems with Alpha, textures doesn't show up in render


So I ran into a problem where some of my textures with an alpha channel won’t show up in my render.
Everything is fine in the viewport but when I switch the viewport shading from ‘Material’ to ‘Rendered’ to preview my work, the textures with alpha disappear.

Here is the viewport in material mode:
And here is the viewport in rendered mode:

As you can see, the eyes and mouth won’t show up for some reason

And here are the settings for my material/texture (I’m not exactly sure what settings are relevant for this, but I’ll take more screenshots if needed)

Also I’m just doing basic shadeless rendering in ‘Blender Render’.

Any help is much appreciated!


EDIT: Nevermind, changed the mapping from Object to Generated and now it works
