I am in rendered mode but I can’t see the texture
Did you map the texture coordinate? A new material will also need to be created to attach the texture to before it can be applied to the mesh.
I basically forgot to create the material, how stupid ^^
No worries 
I still do that sometimes. 
Argh! Had the same problem with the texture not showing up. I created the material, but forgot to ‘assign’ it. After reading this I clicked on ‘assign’ and voila there was texture! Thanks NixeKnox!
