So finally I have finished programming my Picasa integration into Wordpress plug-in to generate galleries with Shadowbox automatically. This is early beta, but at least it works and now galleries page is generated automatically. I can also insert galleries to news post like this:

3DGallery

Description: My 3D renders created with Maya.
Contains 15 photos.

It allows to expand gallery in post, so you are not redirected to galleries page and still can see related text. Now just need to add ability for single images.
