Photos are commonly saved as JPG or JPEG. It is good to save your photograph as JPG for altered colors, gradients, and textures. JPG loses a bit of clarity each time it is copied, due to compression, but is usually not noticeable.

Graphics and screenshots should be saved as PNG if the image contains pointed lines, clearly unconnected areas of flat colors and text. File compression for a PNG is lossless. Lossless compression retains all of the data contained in the file, within the file, during the process. This is important when you have images that are still in the editing process. PNGs are often used if size is not a concern and the picture is complicated because a PNG file holds more information than a JPG. Bottom line,
JPG for Photos, PNG for Graphics.

Incidentally, JPEG stands for Joint Photographic Experts Group, which created the standard. PNG stands for Portable Network Graphics.
