texturing an existing mesh, please help

[Sonck]

hi

there is this mod that doesnt work, Soul Of The Champion. i really would like to have this sword and sinds the author has stopped modding, I decided to try and solve it myself. the onely problem is, i dont have any experiance in blender or nifskope or all that other stuff. i just downloaded nifskope and tried it a bit(i examened another mod to see how it should be). now i managed to get the mesh of the Soul o/t Champion. the problem is i want to give it a texture. the texture that was whith the file was an image of the sword in real life(it exists), not a texturefile like another. i would like to know how I give the mesh a texture.

please help me out

i would like to do this myself cuzz later i would like to make my own sword.

 

edit: i have added the image the author used as the texture
