Sorry, I see what you mean but my response is to dump websnapr from mojoPortal. The bait and switch ends here. It used to be something you could decorate a link with to provide a preview but the new implementation is no link at all but just javascript without an html link.
I'm sorry I ever introduced wepsnapr into mojoportal, it didn't work out great and it is going away as far as I'm concerned.
Those who still want to use it can wire it up themselves by pasting those javascript links into an html content instance in source view and adding the main script to their layout.master file.
Sorry for the inconvenience. In the web world sometimes things come along that are useful and then they go away, so it is with websnapr. It will be removed in the next release of mojoPortal.
Best,
Joe
