How to make home quick display graphics?

[Radames]

There are many web graphics methods which can be used for solving the problem of quick display graphics, but the thing is that I do not have much information related to it. I am a novice user to this field of web graphics, if anybody can help me to understand this web graphic methods I will be really thankful.

Determine the image format. This is important, in the HTML file, using *. jpg, *. gif, *. bmp file formats, etc. all can be viewed. We select only the previous two, because the two file formats can image a large degree of compression, which allows similar visual effects in the production under the premise of the image file size will be much smaller.

In Paint Shop Pro software, the Color drop-down menu, there is a "Decrease Color Depth" feature, which is used to reduce the number of colors used in the image, you can choose one of 16 Colors, about the number of colors used in images be reduced to 16 colors. When the color reduction in the number, if you think that little change in image quality, then use GIF format. To know, JPG format, but all treat color images using 16M colors

If you think that the number of colors reduced significantly worse visual images, so that you cannot tolerate, then we are using JPG compression format. No matter what kind of graphics is to use the processing software, it will be when you save to your question JPG compression ratio. Of course, the more ruthless compression, file smaller, but the image quality is also worse. Typically, sampling 50% to 70% better compression ratio, when the compression ratio from 0% to 50%, the file size will be a sharp decline, while the image quality has not changed much, and then increase the compression ratio, the images will be significantly worse, while reducing the file size is very limited, and sometimes even a reduction of only a few dozen bytes.

In front of the image weight loss method almost say that out, that is the number of bytes the image is no longer reduced. However, we can think of a way in the image file size of certain circumstances, so that visitors can wait patiently and images all out. The method is used progressively interlaced GIF and JPG mode. Interlaced GIF image file refers to the way in accordance with interlaced display, such as the first, surprisingly few lines, and then out the even-numbered lines, resulting in a clear image is gradually changed.

There is a way to let visitors can wait patiently and image display method, that is, use the preview image. Original that is displayed before the first showing a number of bytes is relatively small, relatively poor image quality, image. By the viewer decide whether to visit the Original. Typically, the main image preview images are low resolution, high compression ratio version. Use the preview image is: <img src="temp.gif" lowsrc="preview.gif"$>, which is the Original temp.gif, but preview.gif is a preview map.
