One of the factors that give that talk is the inclusion of images of all kinds - photographs, diagrams, illustrations, multimedia and so on.
Others blamed the images for many of the problems of loading and populating the network utility.
Images attract and distract users alike, it is important to limit the graphics. The reduction of images is also a tool to ensure that their Web are an appropriate size.
Reusing Images
When you use an image, consider the reuse on other pages. Today’s browsers can store images, which means it does not have to be downloaded again the next time a page is loaded with that image.
Reuse also has the advantage of giving the user a sense of familiarity with your site. Within a web resource reuse any type of arrows, buttons, or icons. Or use a different photo on each page of its website, if you wish, but try these images weigh as little as possible, users will thank you.
Web Animations
The animations are particularly troublesome and can lead users away from a site or a site. Do not use animation unless it is really necessary for the content of your page.
The animation can be a valuable tool. The free movement in the web pages, annoys users and ignores the fact that many users have older versions of browsers and do not have the newer playback systems available (contrary to what some believe designers, users not download a plug-in again, because your page as needed).
The most efficient format for your images
Always use the most efficient format for your images. For photographs, use JPEG compression so as possible. Other types of images should be stored using GIF format. Using an inappropriate format can double or triple the file size and transfer time from the server.
Reduce the resolution of the image as much as possible. The reduction in the resolution improves download the image.
An image must be of high resolution only if it is to be printed (as printers require a much higher resolution).
Reduce the number of colors
If possible, reduce the number of colors. Many graphics programs allow you to “posterize” photos, getting a little remarkable reduction of color.
If you use many images, use a commercial tool for image compression to reduce file sizes.
Include images in HTML attributes that will improve performance. Explicit attributes of the display size of the web speed, since the browser does not have to upload the image to determine how much space should be left for this image.
Use the width and height attributes for all images. Also add the ALT (description of the figure) to each image.
