Image Formats Used on the Web
You cannot display any old formats on the Internet. As for page creation, image integration has to obey certain simple rules. The first thing to note is that only three image formats are accepted on the Web:
To do this, simply check the size of your files on your hard drive. A navigation button should not exceed 5KB and a fairly large photo 30KB. Otherwise, visitors might not see your images or want to come back on your pages.
You cannot display any old formats on the Internet. As for page creation, image integration has to obey certain simple rules. The first thing to note is that only three image formats are accepted on the Web:
- The GIF format (image.gif) is used for images requiring few colours (buttons, drawings, graphical texts...).
While this format enables the creation of very small sized images, they can only be composed of 256 colours. Some versions
of this format enable the creation of transparencies or animations. - The JPEG format (image.jpg or image.jpeg) is used for highly coloured photos and drawings. It allows millions of colours in images and can be optimally compressed.
- The PNG format (image.png) is the newcomer on the Web and has positioned itself as a competitor to the GIF format.
It allows the storage of anything between 256 and several million colours. It is not yet widespread but should make its mark
in time.
To do this, simply check the size of your files on your hard drive. A navigation button should not exceed 5KB and a fairly large photo 30KB. Otherwise, visitors might not see your images or want to come back on your pages.
