Not sure how many of you know of Zoner Photo Studio, but there are free and Pro versions, both of which view a large range of photo and graphic files. The reason I mention it, is that it also views XAR files, and the drag and drop functionality from Zoner to Xara actually makes it easier to use than Xara's included Designs gallery. You can even view Ai files (maybe not all of them) and pdf's and drag and drop them into Xara for editing. May be worth a look.
