  Now that the Texture Source Editor is open, click LOAD on the top left hand side to open your first image. Browse through your system to find and select your image, preferable stored in a bitmap file, but you can also use .jpg, .gif, and other formats as well.
  Since I am wanting it to be a texture that has a bump effect, I must also have an image in the "alpha channel", that is the window in the middle of the Texture Source Editor. An Alpha Channel is a special part of an image that is used to hold selections and other odd information . Only more advanced art programs, Such as Paint Shop Pro, Photoshop, Bryce etc deal with Alpha Channels.
  You can use any image for the Alpha channel but I used the same fractal one, so in the first channel (far left) I COPY the image then PASTE it into the Alpha channel. Now close the Texture and Material windows and go back into the main Bryce window. Note that I used a fractal on the blue sphere as well as the pyramid. You can see both fractals in the small gray cells in the pic above.
  Next you render the image and save it out. I always save images out in Photoshop format (.psd) as it's very high quality, easy to work with and Paint Shop Pro (my favourite 2D paint program) works with that format too.

  Now here is a VERY useful tip, when an image is first loaded it is a "background layer". This means that some special effects etc will not work on it, so you need to "promote" it to a true layer.
  (1) This shows opening the Layer Palette, then Right Clicking on the Background layer to bring up an options window, click "PROMOTE TO NEW LAYER" and it then becomes LAYER 1, ready to work on. A faster way is to do this double left click on the background layer's name bar.
  "LAYERS" are an important part of working with images in advanced paint programs, basically you can have stacks of images, one on top of each other. So you can cut bits out of one to see the layer below etc, this is VERY useful, and lets ye get up to all kinds of fun! ;)
