textures on the inside

hey my fellow blender enthusiasts
bit of a silly problem but for the love of god i cant remember how to get around it im texturing an aircraft i have been modelling a mirage 2000 3 but im building textures for the fuselage in gimp and for some reason when i apply them to the mesh they are attaching to the inside and not the outside i have tryed flipping the normals and im not using mirror modifier at this time what the hell am i doing wrong
cheers in advance guys n girls

please help! :o

ops sorry people it was a normals problem i think where i had it on mirror modifier before and removed it swapped the normals over completely i didn’t pick up on this until i turned the normals on visually !
