The colorful web pages you see today are all because of the use of images. If you think about the past, all the web pages on the Internet were plain text web pages, which were very boring, and you will understand the importance of images in web design. Images can be inserted into html pages. There are two commonly used image formats on web pages: JPEG and GIF:
JPEG (Joint Photographic Experts Group) is a file format specially designed for photo images. JPEG supports millions of colors. JPEG is a lossy format, which means that some image data is lost during compression, which reduces the quality of the final file. However, the image data is discarded so little that there is no very noticeable difference in quality.
Graphics Interchange Format GIF is a very popular format for web images. Although it only includes 256 colors, GIF provides excellent image compression with almost no loss. And GIF can contain transparent areas and multiple animations. It compresses by scanning rows of pixels horizontally to find fixed color areas, and then reducing the number of pixels in the same area. Therefore, GIF is usually suitable for cartoons, graphics, logos, graphics with transparent areas, animations, etc.
Inserting pictures into the page can beautify it. There is only one mark for inserting pictures, and that is the HTML web page image tag_HTML/Xhtml_web page production mark. When inserting pictures, just using the HTML web page image tag_HTML/Xhtml_web page production tag is not enough. It needs to be completed with other attributes, as shown in the table below.
