Netscape does not display some images.

I recently partially installed Netscape 6.2.1 on my Win 98 Desktop machine because I would get a fatal error periodically while using Netscape 4.7x. I can not see some images. Instead of some images I get a text hyperlink. I do not have this problemin Internet Explorer or Netscape 4.7x. I just reinstalled Netscape 6.2.1 and let it do a full install but the problem is still there. Should I uninstall and try again or is there a setting I am missing. My friend says it may be the location of the cache file but I don’t know why that would effect some image and not all. Plus, I can not seem to locate the place to change the cache path.
I hope this is enough info.
Thanks in advance.
