I have 168 MRI images to scroll. But my slider goes 1,3,5,6,8,10...almost every second image is shown. I've count them and turn out to be that slider has a exactly hundred steps. How can I increase that steps that slider shows one by one image?
Thanks.

Note that the accepted answer is incorrect. The actual required limits are:
[1/(maxNumberOfImages-1) , 10/(maxNumberOfImages-1)]
^ ^^^ ^ ^^^ missing in the answer
The general solution is actually:
stepSize/(maxLimit-minLimit)
which should make the mistake in the accepted answer clear. See also:

Good catch Stephen. I've made the change in case someone sees only my answer below and not your correction. Thanks!

To setup:
maxNumberOfImages = 168;
set(handleToSlider, 'Min', 1);
set(handleToSlider, 'Max', maxNumberOfImages);
set(handleToSlider, 'Value', 1);
set(handleToSlider, 'SliderStep', [1/(maxNumberOfImages-1) , 10/(maxNumberOfImages-1) ]);
To use and find out which value the user is on:
imageNumberSelected = int32(get(handleToSlider, 'Value'));

The two values for the SliderStep property specify how much the slider moves when you hold and scroll it and how much it moves you click the arrows at the side.

this ('SliderStep' property) doesn't exist in slider object of the gui designer.

I find that hard to believe. Attach a screenshot of the property inspector with your slider properties showing.
