Important note to the "Eejit's Guide"

Since the original guide was published there have been two changes in the way that photographic textures are usually presented within the object file.

Firstly, the .bmp file format has been superseded by the .png file format. The syntax will now be "Load filename.png" .png files are more efficient than the old .bmp ones, you can still use .bmp - just ensure to use the correct extension according to the file type.

Secondly, image transparency. Originally the RGB color value  0,0,255 (pure blue) was popular as a transparent value. However, it is normal now to use mainly absolute black - RGB value 0,0,0 - for transparency. 
Black transparency can help eliminate some undesired color fringeing around the edges which may be conspicuous using "brighter" transparent color values.
Of course, any RGB value may be used so long as it is specified in the line "transparent Rn, Gn, Bn" - where "n" is an integer between 0 and 255.
