JPEG is good for photographs and downloads quickly from the Web, but it can lose image data when you save it. Apple Macintosh designed PICT for the MacOS, but TIFF is a good cross-platform format that you can use with many operating systems.

The terms “Internet” and “World Wide Web” are often used in every-day speech without much distinction. However, the Internet and the World Wide Web are not one and the same. The Internet is the backbone of the World Wide Web. It is the underlying global data communications system, i.e., the hardware and software infrastructure. It provides connectivity between the Internet-based resources and services and the users of those facilities.
In contrast, the Web is only one of the services communicated via the Internet. The World Wide Web is a huge set of interlinked documents, images and other resources, linked by hyperlinks and URLs. These hyperlinks and URLs allow the web servers and other machines that store originals, and cached copies of these resources to deliver them as required using HTTP (Hypertext Transfer Protocol). HTTP is only one of the communication protocols used on the Internet.
