Distortion effects stretch and twist an image to make it look funny. Distortion effects can be used to make a head appear larger than a body or to distort one particular feature of a photo. Many photo editing programs can be used to get the distorted effects, as well as online photo editors.
Comic book photo software and websites let you turn any image into a comic book, complete with funny captions and comic characteristics that allow you to turn a series of your photographs into a personalized comic. Adding free comic effects to your photos can be done with online photo editing websites like Photo Trix, Loona Pix or PHIXR.
Consider using funny cut-out templates to add fun to your photographs. Put your head on a fish, on a ballerina's body or turn yourself into a western gunfighter. Many websites offer free templates that let you upload your images and try them with a variety of humorous templates.
Create morphing photographs that combine two or more photographs into one image. Combine your face with a tiger or lion, or try combining your face with someone else's face. No two results are ever the same, so you can never predict the funny results you will come up with.
