Understanding Pictures

Compression – Making things smaller

JPEG

Best for: Compressing high-quality images

such as photographs and detailed artwork, without sacrificing quality.

Handling subtle shadings and colour blends more efficiently.

GIF

Best for… Images with solid areas of colour Line drawings or logos Transparency effect Animation

PNG

Open Source, no licence required by developers, unlike GIFs.

Widely supported by the Web. Will never completely replace GIF,

as it does not support animation.

Scratch - over to you…

Scratch accepts the following file formats for images or photos: JPG, BMP, PNG, and GIF (including

animated GIF). Find some images / photos on your

computer or on the internet and import them as sprites into Scratch. You can choose backgrounds or characters.
