Alright, here's a time waster that's sure to bring a smile to your face. Check out Photofunia. You can insert your favourite images into templates that are sure to crack you up.
The only catch is that your files need to be 500kb or less. How do you know if yours is the right size? Right click on your image and then click properties. The size will be listed. The site gives you direction for downsizing files but that's only helpful if you speak gibberish. I used photoshop.
Anyway, take a look at my silly creations and then create some of your own. Have fun!
