Step 1: Yippee for Pixlr!
First go to http://www.pixlr.com
I get a lot of my clip art for FREE from Graphicsfairy She has accumulated so many graphics over the years and they're all FREE! But most have a white background to them (what do you want for free?).
Worry no more - you do not need Photoshop to get rid of that white - use Pixlr. So download some clip art and let's go!
Once you're on Pixlr's home page, choose Open Image From Computer and grab your image.
Step 2: Easy Peezy
The Tolerance Setting in the menu bar allows you to change how "detailed" the magic wand is. For this project, choose "3"
Step 3: Let's make Magic
However, we do not want the white part. We want to get rid of the white.
Click Edit from the Menu Bar and choose Invert Selection. This will now flip the dotted line to be around the image (in this case the elephant).
Step 4: Presto, Chango
From the Menu Bar choose File, then New Image.
