[!NewsParserX? &url=`http://rss.news.yahoo.com/rss/topstories`!]
They do have a lot of elements I don’t normally see in these, but can you share the exact call to NewsParserX and/or pieX, and the chunk templates you are using to render these with? That could be part of it...
I tried that snippet also and still had errors with the import. Every other feed is working well (although no others so far have images), but I am wondering if it is a tag or formatting issue specific to Yahoo! which is causing the issue.
