Pictures won’t show on home page

I can’t get pictures to show up on my homepage (www.suicidedictionary.com). I built a different site using the same wordpress theme and didn’t have a problem. The hosts are different (the one that isn’t working is hosted by yahoo…the one that does work in hosted by hostpapa). I am using custom fields, using Image and then copying wp/…. in the proper box. I’m getting a small box with an x in it on my homepage though. How can I fix this? Thanks for your help.
