Image Borders

	First find a suitable picture to put a border around. I chose this one from the Picture Publisher CD.
	Next, create a rectangular mask about 20 pixels in from each edge of the image. Invert the mask, then switch to the alpha channel. You should have something similar to this picture.
	Now apply the Crystallize filter. You may want to increase the crystal size to nearer 30 to get decent results. Experiment with the Preview until you get the border right.
	Next, apply a Gaussian blur, to get the picture on the lower left.
	Finally, let's apply our border to the picture. Switch away from the alpha channel, back to the main picture. Now select the tint fill tool, with a colour of black, and fill the image. You should have a border like this. Possibly one of the easiest effects you'll see, but still looks good.

Border using Twirl filter: Border using Disturb filter:

As a final note, remember that there are other filters that you can use. In the picture on the top left, I used the Twirl filter instead of Crystallize; in the bottom-left picture, I used the Disturb filter. Each one gives a new border that you can use. Other filters should work too, so why not give them a try.
