Add You - The Three Principles of Image Optimization
I wrote something on thinking like Google in the first part of this article. However, I still feel there are issues that I did not address in that article. I'll address them here.Google was not always what it is now. This is very instructive because it will get you into a mode that will make you think better like Google with the attendant profits.Just a few days ago (a few years actually) there was Altavista. Then Yahoo's Directory used to be a lot more than it is now. Oh, there was Excite, too and a few others.But then they made a grievous mistake. Each thought it was king and suddenly, the true kings online dethroned them and made them a shadow of what they used to be.Google
Speeding up image load times
The main idea behind making an image load faster is to make the file size smaller. This can be accomplished in two ways, you can either make the dimensions of the image smaller, or decrease the amount of coding that is required to display the image.

Back in the 19th century, an Italian economist quantified the general relationship between a minority of producers and a majority of output. Sound familiar? The simplified version of Vilfredo Pareto's ratio, known as the 80/20 rule or the Pareto Principle, says that in most cases, 80% of production comes from 20% of producers.Quality guru J.M. Juran referred to Pareto's principle as "The Vital Few and the Trivial Many". If you are running a company the 80/20 rule has powerful implications for every area of your business.Pareto's postulate says 20% of your effort will generate 80% of your results. There is also a corollary: 20% of your results absorb 80% or your resources or efforts.T
All of these problems can be caused by an improperly optimized web page. In other words, the page loads too slowly and your visitor leaves before you have had a chance to hook them.
Optimizing a page for quick load times can be broken down into 3 broad categories: the basic coding of the page, scripts that are used on the page, and images. Of these three, images that are too large can have the most significant impact on load times and therefore have the greatest potential for improved page loading times if properly optimized.
A brief primer on image types
There are many image formats in common use on web sites, the three most popular being GIF, JPEG, and to a lesser extent Flash content. We will be limiting our discussion to GIF and JPEG images, with a specific focus on still images.
Each of these image formats has their strengths and weaknesses. GIF or Graphics Interchange Format was developed by CompuServe before the Internet boom as a way to share images on the CompuServe service. Due to limitations with screen resolutions and color depths at the time, GIF images were limited to showing up to 256 colors, more colors were imitated by Dithering, a process of fooling the eye into seeing one color by using 2 or more sets of color dots spaced too closely for the eye to distinguish separately.
Imagine a chessboard with black and white squares. When viewed closely we can distinctly see the individual squares, but if we back off far enough we will no longer be able to discern the individual squares and instead we will see one large grey square, the black and white squares merging together in our eyes to form one solid color. This is the concept behind dithering.
The JPEG file format on the other hand is a newer format that can handle millions of colors easily. The initial drawback to JPEG images is that they do contain many more colors, and each color requires some coding for display, making the file size larger.

The growth of market economy and competition has shifted the base from sellers to the buyers. Companies today cannot afford to ignore customer's perspective. Companies have to make an earnest effort to gain an insight into customer's viewpoint so as to survive in the market. There can be more than one way of getting feedback from customers to assess a company's performance and prospect. The most important tool used commonly by companies for this purpose is web surveys.Web surveys come handy to the companies because of the technological revolution brought by Internet. Web surveys facilitate understanding of the basic attributes, conduct, perceptions and knowledge of the target group. Surveys make i

One of the most common ways that carwash owners like to advertise their business in their local communities is to use direct mail marketing advertising in those little coupon booklets that are sent out. These work very good however, there are few things that you should consider.First, you do not want to give away too much of a discount and then have all those people show up on a busy Saturday when you are already slammed with customers. Instead you want to make an offer where they have to come on a Monday to stare Wednesday to receive a discount. If the booklet of coupons comes to the home on a Thursday this is not so great for your business. But if it is delivered on a Monday with a big coupon

Speeding up image load times
The main idea behind making an image load faster is to make the file size smaller. This can be accomplished in two ways, you can either make the dimensions of the image smaller, or decrease the amount of coding that is required to display the image.
The easiest way to reduce an images file size is to reduce the image’s physical dimensions. In other words, the smaller the image, the smaller the file size. Imagine an image that is a square 80 pixels by 80 pixels. The number of pixels contained in the image is 80x80 or 6400 individual pixels. If we reduce the image size by one half to 40 pixels by 40 pixels we then have 40x40 or 1600 pixels. So reducing the image size in half reduces the file size to one fourth of the original.
This is our First Principle of image file reduction: Use the smallest image dimensions that will work with your layout. And likewise the fewer images on the page, the fewer image pixels, therefore the smaller the page size.
Since GIF and JPEG image formats use different methods of saving image information, they tend to be better at showing some types of images and worse at showing others.
GIF images, since they are limited to 256 colors per image, are better at displaying images with large solid blocks of color and images with very small physical dimensions. The GIF format will produce smaller file sizes than JPEG for these types of images.
JPEG images are better at showing gradients or subtle changes from one color to another. Therefore JPEGs reproduce photographs very well, or any other image with gradations. The JPEG format will produce smaller file sizes for these types of images than the GIF format will.
This is our Second Principle: Choose the correct image format for the image you are using. Most web pages will contain a combination of GIF and JPEG images.
Decreasing the coding is called image compression. Both GIF and JPEG images can be compressed but the process is different. In GIF images we try to limit the number of colors, in a JPEG image we use software algorithms to remove redundant information from the file.
Whenever we compress a file we will lose some image quality. We have to reach a balance between a small file size and acceptable image quality.
This is our Third Principle: Find the least acceptable level of image quality.
