Portfolio images not showing up in carousel

Hi, I finally got the carousel to work for my portfolio using this snippet: [tx_portfolio items=”6″ columns=”4″ hide_cat=”no” hide_excerpt=”yes” carousel=”yes”]. However, now my images aren’t showing up. I do have GD Library enabled and TemplatesNext Toolkit. Why else wouldn’t my images show up?

I would paste my url except the site is on my internal server and cannot be viewed outside. I hope you can still help me…

Thanks so much!!!
