Thanks for the help so far. I made your recommended changes. As for
the ->findAll() issue, I've found that in dbo_source.php on line 577,
$linkModel is null, which in turn means the db connection stuff on
line 580+ fails because $linkModel->useDbConfig doesn't exist on a non-
object. Do you think this is a bug in the 1.2.0.5427alpha code, or am
I missing a declaration somewhere? (Maybe this is related to why $this-
>Image->Tag->save() doesn't work... Image not having any saved
references to Tag?)
Here's a var_dump of the Image model, just before the error:

Looking at the dbo_source.php code again, the '$linkModel =& $model-
>{$assoc};' uses the key part of the ["hasAndBelongsToMany"] model,
but even if {$assoc} == 'Tag', $linkModel still comes back as NULL.
