Textured view Pb

Hello !
I have to ask this: i m stuck.

When i aplly an image texture to an object, ( even the simpliest image on the standard cube), and selected “textured view”, i cant see the texture in the viewport…
I know this works, i ve done it before. I cant remember how though…
Is it only possible with UV mapped images ?

You guessed right, only UV-mapped textures will show up in textured mode

ah ahhhhhhhhhhh
I ll do quick UV then: i need these pictures as references in the viewport.
Thanks !
