Hi there,
try this:
You want to have both images in one div if you want to align both next to each other. Then you control #container and align it horizontally and vertically.
And also important tip, in HTML, when you use an ID, it is intended to be unique, so you can only use it once on that page (i noticed in your code you had used #container twice). If you need to use the same code, then switch it to a class, which you can use as many times (.container) :)
Hope that helps.
