is some slick software. First of all the user interface has some very smooth graphics. It just feels high class.
Picasa2 is Google's image editing and organizing software. When you download it, it will search your disk for all your images. It creates its own time-line sequence of folders, which it maps to your folders. (That is its worst feature. To do a good job it has to keep up with changes made to the file system. Often it doesn't.)
It does have a nifty timeline display capability. It also has a nice picture editor, and it links smoothly to Hello, which lets you put pictures on your blog.
All-in-all they did a very nice job.
