Xara aren't really helping users by naming a widget "Inner Zoom 1 Widget" which can be found via the online Content Catolgue Search but naming it "Landscape Cloud Inner Zoomer " within the widget which can't be found via the online Content Catolgue Search

I did get your zoomer to work, however I don't understand (and it's not intutive) to need to:

Find WTag:image(768):imagebig and rename to WTag:image(4096):imagebig.
