Slide preview different from published/entire project preview

Im pretty new to Storyline so sorry if this is a common problem or if I'm doing something wrong. I couldnt find an answer online.

I've made a memory game and it works pretty well. I used a Question Bank to make 5 random memory games. The problem I have is with the way images are being displayed.

When I preview an individual slide everything looks great (as in the first screenshot). But when I preview the entire project or publish it there's something wrong with the images (see second screenshot). Suddenly the cat is sticking out of the black box. I also added my entire .story file.

Am I overlooking something here? Any help would be greatly appreciated.
