There are number of simple and quick ways to optimize images for your blog or website. Combination of following steps shouldÂ work wonders.
1. IMAGE FORMAT
Every image format is different and is used for specific type of images for optimized results. For example for logos, buttons, vector like defined structure – GIF format should be used. For usual images with true life colors – JPG format should be used. For better transparency & finish use PNG (rarely used).
Quick Tip, incase you cannot decide which format should be used for a specific image – save a specific image in 3 different formats JPG, GIF and PNG. Compare the resultant image size and clarity to make final decision.
2. IMAGE SIZE
Lesser the size of image, faster it will load. You can reduce size of image by reducing image resolution like reducing pic from (1024X768)px to (800X600)px, selecting appropriate image format (see step 1).
Quick Tip, if you have Adobe PhotoShop on your computer – while saving images instead of using file > Save option use file > Save for Web option. Save for web option provide you preview of image in different formats and quality levels for quick selection. You can also use Online Image Optimizer.

Quick Tip, always use dash while using multiple words in an image name like microsoft-logo.jpg Search engine also understand underscore, so you can also rename image like microsoft_logo.jpg
4. IMAGE DESCRIPTION
While posting images on a webpageÂ make sure you add some unique description to all images. You can use ALT tag for this purpose like: <img src=”http://www.tothepc.com/microsoft-logo.jpgâ€” alt=”â€Microsoft & Bill Gates” />
Quick Tip, besides the ALT tag you can also use TITLE tag for more decription like: <img title=”Bill gates launch new Microsoft Logo” src=”http://www.tothepc.com/microsoft-logo.jpgâ€” alt=”â€Microsoft & Bill Gates” />Â
