[Plugin: SlideDeck 1 Lite Content Slider] Image size problem

Hello!

I can’t seem to find the correct image size for slide deck lite.

Every time I upload an image, despite of being in the size of the slide deck, it doesn’t work at all. It shrinks, a lot of background appears.

Anyone with this problem?

Cheers!
