# Take a photo of some ribbed concrete with a digital camera, preferably with some marks to show 1 square metre.

# Upload that photo to your computer, then, in your photo processor (iPhoto on Mac; [[GIMP]], [http://www.irfanview.com/ IrfanView] or any other on windows), ‘Crop’ it to show just the square meter, and export it with a good highest detail/lowest file size compromise ("export to web" in iPhoto).

# During that export procedure, select a pixels size which is compatible with FlightGear - that means its resolution must exist of squares of two (e.g., 2<sup>1</sup> = 2, 2<sup>2</sup> = 4, 2<sup>3</sup>=8, 2<sup>4</sup> = 16, etc.). That gives you possible resolutions like 2x2, 2x4, 8x32, 256x16 and all the like. If you don't do this, FlightGear can show the image, but only after a resizing procedure, which eats up processor capacity. So you want to do that for FlightGear before applying the image to your model. You can re-scale distorted images in SketchUp later again.
