That's a really interesting comment, and may contain a big clue. I assume you are looking at the web page source as seen by your browser. If that is true, then that source is very different from the source I'm feeding into WeatherCat - and that in turn may be what is leading to a bad list of files to upload. First a couple of comments on the html, then the now-current html, then the html source itself.
First, I'm not sure why the <div class="yui-u first"> and <div class="yui-u"> columns have been displaying properly without the second one being identified properly as <div class="yui-u second">, but they have been (at least when I did my initial testing two years ago on a local apache server, and on the Apple server) - but whatever, the source has now been fixed and the first column is <div class="yui-u first"> and the second column is <div class="yui-u second">. As you can see, that did NOT fix the problem.
I would also note that the missing files are NOT all in the first column, there are four JPEGs missing from the first and four more from the second. If there is a <div> that doesn't have a matching </dev>, neither I nor BBEdit (Balance Tags command) is seeing it.
The relevant html source I'm feeding to WC is below:
