Very competent software with a whole host of features...more than ample for the home user. Much more to play with than in Picasa.
You can get an earlier version ( version 9 ) for £9.99 (downloadable, no disc.)... or an even earlier one, version 8, for free ( downloadable. no disc ) from

The only problems will be that they are quite large file to download and they require on-line registration, and when Serif have your e-addy they plague the life out of you with offers etc.
Worth a look. For me the later versions of Photoshp Elements have been spoiled by the inclusion of "image organisers" and "photo galleries" which have bloated them out, increased the cost but which do not much more than Windows "My Pictures"
