My images aren’t showing up with new theme?

I’m hoping someone can help me?

I uploaded a new theme and all my images are not showing up, and I can’t for the life of me figure out how to get them to???

Also, this theme is supposed to have a “big Feature Category” at the top, and that also is not showing up, even though I have posted a new Feature story???

Does anyone know how to resolve these issues?? Please???

Thank you in advance,
Kat
