Picasa is a great, free piece of software for photo management on your PC. It’s very easy to pickup for anyone with basic PC skills and it covers all the common things you want to do with your photo’s once you transfer them to your PC.
Having recently forced myself to use Picasa I have become something of a convert so I thought I would share a few thoughts on how it can be used.

Installation: dead easy… simply follow all the default options (next, next, next)
Getting Started: the first time you run Picasa you will notice it starts scanning your PC for common places where you keep your photo’s, for example it will look in “My Pictures”. This is great for a start but you will want to put a little more thought into configuring Picasa to keep an eye on the folders you want it to look at. One of the cool things about Picasa is that is constantly checks for new pictures in the folders you choose (selecting these is covered next) so you don’t have to keep re-configuring, think of Picasa as a central place to look at all your pictures from across all of your PC and external drives.
Configuration: you will want to select specific folders on your PC and external drives for Picasa to monitor, to do this click on the File menu and choose “Add folder to Picasa”. The dialog now lets you browse through folders and drives on your PC to choose which ones should be used. Pick all the locations you keep your pictures (and where you upload your new ones from cameras) and select “Scan Always”. Picasa now updates itself whenever you add new pictures to the folders you selected. Once you change the configuration and hit OK you will see Picasa re-scanning to pickup the new photo’s in the new locations.
Browsing photo’s: now that you have all your photo’s visible in one place you can start to use Picasa to look at them. Your photo’s are arranged in time order with the newest ones at the top, you might need to set the time of your camera’s for this feature to work properly! Scrolling your mouse wheel or using the slider on the right hand side will take you back through all your photo’s and on the left hand side of the screen you can see all the folder labels where each of the pictures actually resides on your PC. In the bottom right hand corner of the screen you will see another small horizontal slider, this makes the picture thumbnails bigger or smaller so you can see more or less pictures at any one time.
Opening photo’s: to look at a photo full screen all you need to do is double click it and you will automatically open the picture in a basic editing tool. There are arrows at the top of the screen to scroll through more pictures or you can use your scroll wheel to browse full screen.
Editing: I don’t generally use Picasa for photo editing because it’s very basic, but for simple tasks like cropping, getting rid of red eye and for automatically correcting colour it is very handy. On the left hand side of the editing window you can find the different options for edits and effects.
One thing I was not able to find was a re-size option, this would be handy for reducing image size before uploading to the web but it’s not entirely necessary.
Creating Albums: back in the main “Photo Library” screen of Picasa you will notice in the left hand side you have Albums and Folders. Folders are the names of the folders on your PC where the photo’s are stored and Albums are a neat way to group together sets of photo’s so that you can show them in a slideshow or upload them to the web.
For example, you come home from a holiday with 300 pictures on a memory card, you’ve put all the pictures onto your PC (maybe you might use Picasa’s Import facility to do this next time) and you’re looking through them one by one. You might want to pull out a handful of good photo’s from each folder to show to your family and friends without having to bore them with all the dodgy photos of blurry sunsets and stray hotel cats. Picasa lets you add selected pictures to an album by right clicking on a picture (or multiple) and choosing “Add to album”. Now when you show off your holiday snaps you need only show the good ones by displaying the Album instead of all the photo’s from the camera.
Showing off your photo’s: so now you have your Albums arranged with all your holiday snaps and you want to show them off. You have lots of choices at this point (double click or right click on the album in the top left of your screen for some of them) I will list a few of them and leave you to explore the rest.

I am fairly new to Picasa so feel free to comment if you found something I missed. It’s quite likely i will post about Picasa again in the future when I get to grips with all it has to offer.
