When you import textures in Google SketchUp, you will have three options. Use as Image. Use as Texture. and Use as Matched Photo. The Use as Image option will import image as if it were a billboard. The Use as Texture option will import the image as a repeating texture, like wrapping paper. If you select the Matched Photo option, you will automatically be taken to the Match Photo interface, where you can align perspective lines to create a 3d model from the image.
