basic texturing question

This questions probaly asked a lot, but ive barely started on this model and a problem that ive always had is the texturing stretches vertically, idk why, in the texturing ill click to repeat the texture but still i get a outcome like this, could someone please tell me how to fix this or a good tutorial on it, thanks (:

Its the way the texture is mapped on to your mesh. The best way to texture it would be to UV unwrap and texture. More work but you’ll get much better results. If you go quick and cut corners expect to see the lower quality results.
