After reading the blog post, I thought I would delve into Picasa and see what I can do with it. (Although I do have a collage as my new blog header, I didn't do it in Picasa, I used Photoshop Elements.) Surprisingly, creating a collage was extremely easy. There are different layouts you can choose from...I liked the square boxes...speaks to my sense of symmetry. Hmm, who knew. I'll have to see what else I can do with Picasa.
I thought I would share what I created. Note the bottom two are a series of old photos I scanned--they are not as clear as the digital photos. :)
