For all your Lua needs, remember to check first:
  • 2. the official book, http://www.lua.org/pil/ for more friendly and verbose explanations. Ideal to learn. It should also cover most of your needs, as it introduces some data structures, algorithms, etc, which help you getting familiar with the language.
I strongly recommend bookmarking and studying those.

another good lua reference: http://pgl.yoyo.org/luai/i/_

You could combat gaps by:
1) making your images overlap a little (so a bit of shift is ok)
2) placing images relative to each other.
eg: img1 at img1.x, img2 at img1.x+img1.width, img3 at img1.x+img1.width+img2.width, etc
3) use a package to handle the scrolling (eg http://love2d.org/wiki/index.php?title=CAMERA)

Thanks for those, I was having a hard time finding a good learning source but the book is exactly what I was after. :D
