Provides simple drag & drop image gallery functionality to enable you to display Google Picasa Web albums in your WordPress installation.
It looks like Google just depreciated "OAuth 1.0 for Web Applications", so this plugin doesn't work any more... Any chance of updating the plugin to the supporting Google authentication service? https://developers.google.com/identity/protocols/OAuthForWebApps
Would advise against buying this as it looks like its no longer being supported.. too bad.
It does not display albums, just the thumbnails
