how to disable image caching

I want the images loaded from URL. the images may change every week. the slider won’t load and show new images on the URL. what should I do to disable caching? I also cleared app’s data but couldn’t get new Images. here’s my code from sample:

for (String name : imgList) {
TextSliderView textSliderView = new TextSliderView(mActivity);
            textSliderView
                    .description("")
                    .image(mActivity.getString(R.string.temp_url) + name)
                    .setScaleType(BaseSliderView.ScaleType.CenterCrop);
            textSliderView.bundle(new Bundle());
            textSliderView.getBundle()
                    .putString("extra", "");

            mDemoSlider.addSlider(textSliderView);
}

@erlangp thanks for your time, But I figured some other way to pass through this problem. I hope it helps others who have my problem
