Have you considered using Frame Animations?

You can specify an xml in your anim folder that contains a frame-by-frame animation, specifing each image duration, and other settings, check it out

UPDATE

You can also build a frame animation programmatically of course:

    AnimationDrawable animation = new AnimationDrawable();
    animation.addFrame(getResources().getDrawable(R.drawable.image1), 100);
    animation.addFrame(getResources().getDrawable(R.drawable.image2), 500);
    animation.addFrame(getResources().getDrawable(R.drawable.image3), 300);
    animation.setOneShot(false);

    ImageView imageAnim =  (ImageView) findViewById(R.id.img);
    imageAnim.setBackgroundDrawable(animation);

    // start the animation!
    animation.start()

you can use the CountDownTimer : follow these steps :

1) declare an array which will contain the identifients of your pictures

2 ) declare the CountDownTimer like this :

int i=0;
new CountDownTimer(10000,1000) {

                @Override
                public void onTick(long millisUntilFinished) {}

                @Override
                public void onFinish() {
                    imgView.setImageDrawable(sdk.getContext().getResources().getDrawable(array[i]));
                    i++;
                    if(i== array.length-1) i=0;
                    start();
                }
            }.start();

create blink.xml

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/selected" android:oneshot="false">
<item android:drawable="@drawable/Picture_1" android:duration="10000" />
<item android:drawable="@drawable/Picture_2" android:duration="10000" />
<item android:drawable="@drawable/Picture_3" android:duration="10000" />
<item android:drawable="@drawable/Picture_4" android:duration="10000" />
<item android:drawable="@drawable/Picture_5" android:duration="10000" />
</animation-list>

put blink.xml in drawable folder and in activity Code write this.

ImageView mImageView ;
mImageView = (ImageView)findViewById(R.id.imageView); //this is your imageView
mImageView .setImageDrawable(getResources().getDrawable( R.drawable.blink));

then you will get what you want.!

Create a Runnable that executes the change you want (I suppose it will be changing an ImageView's bitmap/drawable), and post them with delay to the main thread loop, using a Handler and its postDelayed() method.

To make it a loop, you could have the runnable post itself.
