DISCUSSION: Why don't you use `imageIndex = (imageIndex+1) % imageResIds.length`?

Instead of using 

imageIndex+=1;
if (imageIndex == imageResIds.length) {
imageIndex = 0;
}

On could type:

imageIndex = (imageIndex+1) % imageResIds.length;

Saves time and ensures the index will return to zero whenever it reaches the maximum length/size. I find it easier too, whenever I need to make changes to whether the increment must occur before or after updating the status of an object. It's definitely not a big difference, I just learned this in one of my classes, where we worked with RingBuffers.

How about this subtle difference imageIndex = (++imageIndex) % imageResIds.length;
