Here's How
the background image was created.

 
I wanted a background image that was uniform, hinted of flowers,
and didn't interfere with the readability of text.

At Stanley Park, photos were taken of a field of Black-eyed Susans.
No single image was perfect, so I chose two and used Photoshop
to put them together.
 

Image 1 scanned into layer 1.	Image 2 scanned into layer 2 and copied into layer 3.
Image 1 positioned directly above Image 2.	Seam was smudged eliminating line where images meet.
Flowers cut out of Layer 3 and positioned slightly higher up.	All layers merged together and image cropped.
Image spattered for painterly effect and desaturized to tone it down.	Top area copied & flipped to the bottom.
Bottom smudge-blended.  Canvas width was doubled.  Image layer copied & flipped horizonally (for tiling on larger screens) and positioned together.
Dark and light areas eliminated with smudging and rubber stamping.
Not enough flowers!  Made a selection of a flowered-area and copied it onto a new layer.
Split the image (for vertical tiling) and positioned at top & bottom.
Merged all layers.
Finally, by reducing the contrast & brightness,  stretching the image and reducing the file size to 17k, we have the final image.
