If I try to take a photograph of, for example, running water, using a slow shutter speed, the image appears white. What seems to be happening is that while the shutter stays open, too much light leaks into the camera.
I want to create something like this:

You're over-exposing.
For running water I often like to use 1/60th second just to indicate some movement. If you go for several seconds, the water will appear completely cloudy - also a great effect. The shot that you linked to was probably around 1/20th second.
To keep the shot properly exposed with longer shutter times, you'll have to use a large f-stop number and a low ISO setting (or film).
If you set the camera to ISO 100 and use shutter-priority mode, then set a shutter time of 1/20th, the cameras built in light meter should do a great job with the rest. Also, you'll want to use a tripod with those longer exposure times.
You can experiment with different shutter times to see what effect you like best.
If you find that your camera *still* lets in too much light, you'll have to go GLH's route and invest in filters.
Best of luck!

If too much light is getting into your camera yet you want a slow shutter speed then you have two basic options (assuming you've done the obvious thing and closed the aperture right down first):-
1. select a different film (assuming you are using film rather than a digital camera!). Select one with less light sensitivity. For example if you are using ASA400 film trying using ASA100.
2. Even easier - put a Neutral Density Filter over the lens. ND Filters are available with different degrees of "darkness" and simply act in the same way as a pair of sunglasses do to protect your eyes from excess light. I use two ND filters of different densities which can be used either singly or together to give three different degrees of filtering.
I frequently photograph waterfalls using ASA400 film and I find that a shutter speed of 60-125 is easily enough to get that blurred milky effect of the water without resorting to ND filters in most instances - but then most of the waterfalls I photograph are in fairly dark gorges in the English Lake District!

I have taken thousands of pictures over the past 30 years, and there are several things that a photographer must take into consideration when taking photographs.
There's the ISO, the shutter speed, the aperture, and then the various filters they might want to use to get the desired effect they want to achieve.
The ISO, shutter speed, aperture and some filters all effect the amount of light in your photography. To take great photographs is a balancing act of composition, shutter speed to get the sharpness required, aperture to get the depth of field that's desired, and so on.
Some photographers spend hours and even days waiting just for the perfect conditions for their photograph, while others are like hunters after their prey.

You need to set your aperture to a larger number, smaller opening, If you go to shutter priority mode and pick a speed of about 1/30 your camera should pick an aperture opening so it does not over expose your picture. That is what causes the white spots in your image

Hi, I recommand you to try google picasa.
picasa is a Google's photo software. It's what should've come with your camera.

Set the aperture to as high of a number as possible

it sounds like you are overexposing your pix. try bracketing the shot. this means you take 3 shots, one at correct exposure, one at one stop under and the last at one stop higher. all photography is an educated guess so dont be put off :)
