ooph...alrighty, well there are a lot of good tutorials on how to work with materials and textures all over the web.
For starters:
- open up the slate material editor. Rendering menu -> Material Editor -> Slate Material Editor
- under the materials standard group, grab a standard material and drag and drop it into the main grid area.
- scroll down to the Maps standard group and drag and drop a bitmap map into the grid area.
- a dialog should pop open that allows you to pick whatever ship image you want for your reference.
- click on the circle node on the left of the bitmap object int he editor. drag and connect the rubber band to the circle where it says diffuse color on the standard material you created earlier.
- right click on the material and check "Show shaded material in viewport"
- select the plane you created earlier in your scene
- right click on your new material and choose "assign material to selection".
- now in the modify panel in your scene, scroll through the modifier list and choose UVW Map
- in the parameters for the modifier, select planar, uncheck real-world map size, and continue to play with the other setting until the plane looks the way you want.
