Lisa,
First off, you can't take too much of our time. We're here to help our users, and support is something we take very seriously. So, feel free to ask anything and be persistent. There may be times when it takes hours to get a response, but that's just our schedule.
For the description setting selection of "Meta Data", the character/word count setting shouldn't matter. When set to meta the full meta description should be set as your og:description tag. On your example articles, I am seeing that behavior. If you're not, let us know.
Finally, for the og:image, we've been doing a bit of testing today. There is definitely a bug in the ordering of insertion when you have all of {SCOpenGraph }, automatic, and default tags. Fixing them all will take some effort, and we'll be investigating the best way to do so. If you're ok with not using a default tag for now, then there's a code change which should fix things right up for you. If interested, edit the /libraries/sourcecoast/openGraph.php file. Around line 211, you'll see:
function addValue($value, $isFinal)
{
$this->value[] = $this->getCleanValue($value);
$this->isFinal = $isFinal;
}
Change that to:
function addValue($value, $isFinal)
{
if (is_array($this->value))
array_unshift($this->value, $this->getCleanValue($value));
else
$this->value[] = $this->getCleanValue($value);
$this->isFinal = $isFinal;
}
Test that out and let us know how it goes. Again, we will look into a way to make sure the ordering is right for all 3, but I won't have an answer immediately.
Thanks for your patience,
Alex
