I'm terrible at technology. I don't understand anything. What is GIF,JPEG, PNG and how do I find it? Get things to be in it? Thank you!

Those are the kinds of file extensions that an image can be. GIFs (graphics interchange format) are usually (but not limited to) moving graphics but can also be regular images. JPEGs (named after the Joint Photographic Experts Group that created it) are compressions of photos and are the most common kind of image which is used in digital cameras, etc. A PNG is a portable network graphic which means that it can be used nearly everywhere and is sometimes superimposed on other images because it fits in. It's kind of hard to explain a PNG, but if you use Microsoft Paint, it's similar to the feature that allows you to move part of an image around and change it so that the white blends into its background...sorry if I didn't help much. ><!

That actually helped a lot. So what if I wanted to convert a picture into one of those?
