Fun happy birthday images include animated GIFs featuring cartoons, words and images; fixed images with a variety of birthday messages; and birthday greetings for specific relationships and messages. Animated GIFs are brief clips from movies, pictures animated in sequence, or graphics that move or light up with a variety of birthday greetings and messages. These animations typically include birthday messages and greetings overlaid onto an existing image or movie scene, with graphics added to enhance the birthday theme.
Fun fixed images conveying birthday greetings include images with animals, babies and small children, and stick figures engaged in a multitude of poses and activities. These images are generally designed to convey the unexpected joy of birthdays at a young age or the inevitability one tends to feel for later celebrations. The images often have text as a caption or written into the image, conveying messages such as "You know you're getting old when the candles cost more than the cake" and "As you get older, three things happen. The first is, your memory goes. I can't remember the other two."
Many fun birthday greeting images and GIFs are available free from websites such as SayingImages.com, PicGIFs.com and AllImagesPictures.com. Sites such as these have a wide selection of fun birthday images available to download.
