Chuck... this is certainly weird!!!! Thanks so much for the help and the quick feedback!!!. The issue isn't getting it to work in wordpress. I can't even get it to work in rss2html - the links i used are using the latest version the I downloaded and installed. I realize that, for whatever reason, it isn't parsing the HTML being generated from photopost.
I'm wondering if there is just a setting with rss2html that isn't parsing properly on my site and does this automatically for Yahoo. Now using the feedforall site the photopost feed DOES work - so I apologize.
But there still is a compatibility issue "out of the box" with some alternatives although I'm not sure the PP is "per se" a problem but rather that they all work a certain way, PP may be compliant but these "standard" tools don't care, lol. I'll keep you posted with what I discover...
and as always, thanks SO much for the great support.
