you forgot the . in $('.top-caption') line 3 as well as in $('.bottom-caption'). not entirely sure what's wrong with the image portion. If I figure it out I'll post it here.
** So you do just need to change $('img') to $('.img') Once you do that click save, then click the link in the objective section (Here's what it looks like). It will show up correct there, mine still doesn't work in the preview window though.
