Here's a great way to turn 2 or more of your favourite digital photos into a
collage. This free web service allows you to upload your pictures then choose
a collage layout for your collage, from dozens of options. Once you're done,
you can add text and shapes. You can change the size, font and colour of the
text, and drag everything around with the mouse to get it pixel-perfect. You
can even pan the images and change their sizes easily. It doesn't get any
easier than this and it's free as well.
