If `seekForwardOnly` is set to true and if we we have moved to `n` image, then
getting details for `n-1` image should throw IOOBE. `minIndex` will be updated
accordingly when `seekForwardOnly` is set to true, so nothing extra needs to be
done from our side.
Naming the function as `checkNegativeImageIndex` is not right, so i have
updated the function name.
