This is a really nice plugin, but please note that it isn't setup to do relative paths (yet?). You will have to manually re-insert the psd file (or choose your own original). I think this is a little snazzier (and much quicker) way of previewing psd files when using this qtz / plugin combo than the supplied example qtz that comes with the plugin, which requires that each layer be manually setup. That can be a bit unfeasible for many scenarios.
