Can anyone please tell me how we can optimise images in web pages for making the website search engine friendly.

There's not much you can do with the images themselves. Image SEO comes from placing the appropriate ALT tags and description on each image that you embed in your HTML.

Whatever you keywords, try to incorporate them into the image's ALT tag. Don't keyword stuff the tag too much, just enough to describe the image and sneak in 1 or 2 plugs.

Compressing your images to appropriate web sizes will also make it more likely to be picked up by Google (this one's a hunch).

Add ALT tags, image size, description so that it will be "readable/viewable" search robot.

When you resize your image on your web page to the size of a postage stamp, you really have not done anything to the image file size at all. What you are actually doing is telling the browser to re scale the image on the fly. This creates a lot of work for the browser. The image that you thought is the size of a postage stamp is still that same large 8 x 10 inch image that takes over 2 minutes to download.

When you use an image editing program to resize the image, and you save it as a JPEG or GIF, you have actually created a smaller image. Now that postage stamp size image that you saved as a postage size JPEG will now load quickly on your visitor's computer.

GIF and JPEG: Two Image Formats You Need to Know About

If you want to optimize your images the first thing you need to know about is the two image formats recognized by your web browser. These are GIF (pronounced jif as in Jiffy Peanut Butter) and JPEG (pronounced Jay-Peg). Both JPEG and GIF are compressed. That means that information has been organized inside the file in a special way in order to minimize the file size.

The difference between JPEG and GIF is the way that they compress the data. JPEG compression is designed to optimize photographs or images with fine gradations of color. GIF compression is designed to optimize images with large continuous areas of color, such as illustrations.

Notice the more you compress a JPEG image, the more artifacts you begin to see. This is because you are actually loosing information. JPEG compression is therefore called lossy compression. You may also notice that the color fidelity does not change.

Colors are not lost in JPEG images. When you use JPEG compression you will trade off between image quality and image file size.

GIF is a lossless compression. Data is not lost. However, color fidelity is not preserved. This is because GIF indexes or limits the total number of colors to 256 or less. When using GIF compression, you trade off between color fidelity and image size.

In the example above the 16 color image gives acceptable color fidelity and its file size is almost as small as the 4 color image.

One way to optimize an image file is by adding an alt tag to it. This will allow you to rank in visual search results.

use some html tags like, alt tags... so that your images can be crawled by SE

use html and alt tags in targeting your keywords.

very well explained.

This is more two years old thread.

There are few effective tricks to optimize images and putting your url at the image can help too for recognition of your image even when others steal it..
