I have the shashin plugin enabled and there are a couple of issues:
NOTE: for development reasons, WP is installed on a subfolder and that COULD be the issue, but Toppa's FAQ page doesn't answer a couple of things.
1) Is the plugin supposed to pull images directly from a Picasa album? Toppa has a FAQ that reads:
Why store all the album and photo metadata locally? Why not just read the Picasa RSS feed on the fly?
OK, so why is it billed as something you can use directly with your Picasa account? If it has to work with locally stored data, then where's the instruction for that? Do I enter a URL from the media library?
2) Why can't I seem to open a new browser window when I've selected that under Settings>Shashin>Open in new browser window
NOTE: The instructions also tell one to configure Shashin and Highslide (now included with Shashin download, BTW) in the Options tab. With 2.5.1 it's done via the Settings.
