Swipe is not working properly when there are less than 3 images

[mig-hub]

Hello,

Basically if you put only 2 images in the slider, you can swipe but you don't see the next image until you release your finger. Which means there is no clue that there is another image and it makes the animation slightly jumpy.
This is only when you swipe from right to left (next image).
It works alright from left to right.

Thank you for sharing this plugin,
