Widget-like image gallery is still work in progress, but functionality is now good enough. File is most suitable for blog sidebar. Code is small, only 60 lines and only 3 functions: move(), adjust() and setToStage().
If you would like to have this gallery for free (with your images, off course) on your blog, email me at flanture [at] gmail. You can have as many images as you like. Colors and links customized.
Next, I will do is stop and resume rotation functions, scale images on sides, info button. Later on I'll try to make xml driven component from it.
