Windows Version of iPhoto
The function of iPhoto is to allow you to sort and manage the burgeoning digital photo catalogs. I have had a digital camera for only about 18 months, and I have nearly 3,000 images on my computer. I talk to some people, particularly professionals, and they tell me stories of tens of thousands of images. Being able to find and sort through those catalogs quickly is a must. Fortunately, there are two great products for Windows users: Adobe PhotoShop Album and Google's Picasa.
Adobe PhotoShop Album comes in two shades: free and almost free. Both versions of Album allow you to import images from your camera or Image Vault and will then store and organize them. You can search for images by date or create tags that you can apply to groups of images. Album also gives you the opportunity to get creative with your images. With a nice set of wizards, you can create professional-quality presentations, albums, and other cool scrapbook-like gifts.
If you like Album, you can choose to pay the extra $39 to release additional features such as a cool calendar tool you can use to find photos from a specific date.
Google's Picasa is very similar to Adobe's PhotoShop Album. You have the amazing search and collection features you expect of Google. It is also very easy to find images. In addition to still images, you can also search videos in AVI, MPEG, and ASF format.
What I find lacking in Picasa are the tools that let you do stuff with your images, such as creating a scrapbook. The only creative tool that is available creates a montage of a selection of images. The effect is very good; I just wish there was more.
