Try using getResources().getIdentifier to create array of drawable id's if drawables name is as img1,img2,img3,.. 

int[] imgIds = new int [100];
int imagecount=1;
for(int i=0;i<100;i++){
imgIds[i]=getResources().getIdentifier("img"+imagecount,
                                           "drawable", getPackageName());
imagecount++;
}

if your images are all called with the same prefix and the only thing it does change is the number you can do the following thing:

Suppose you numbered from 0 to size -1

ArrayList<Integer> imgIds = new ArrayList<Integer>();
for (int i = 0; i < size; i++) {
  imgIds.add(getResources().getIdentifier("img"+i, "drawable", getPackageName());
}

check for typo. Edit. With array:

int[] imgIds = new int[size];
for (int i = 0; i < size; i++) {
  imgIds[i] = getResources().getIdentifier("img"+i, "drawable", getPackageName();
}
