So today we are going to focus on creating image sprites to reduce http requests and hence gaining speeds.

What are Image Sprites ::

This might be the question arising in your minds that what are exactly are image sprites I am talking about, well image sprites is the collection of images bundled into one single image for single http request and fast blog. Well your blog contains many images like it can some small feed icons, email icons and other stuff when someone loads your blog all the images are cached using many http requests and hence more requests are created that slows your speeds. So creating one image and showing part of image where its needed can be easier way.

So implementing image sprites earlier was a headache means you needed to have perfect CSS knowledge for positioning your images and blah blah, but with modern online tools such as SpriteMe that makes your process just one click. SpriteMe can easily show all the images that can be sprited in your blog and creates a image sprite for you easily.

  1. spriteme-spritesVisit SpriteMe.org and drag the SpriteMe JavaScript link to your bookmarks bar, using this link your can easily create sprite fro any webpage by just clicking on it.

  6. So now after your one image is created just click on the export CSS option to see how you can apply that one image instead of many images.
  7. Now you can see the temporary image is created, make sure to download and upload it to your own server or blogger server. You can also see the CSS modifications as you can see just search for the CSS styles as mentioned and change the image url with the one mentioned and also add the position.
  8. Now make change to all the CSS styles and you will have one image sprite running on your blog containing all the images and hence http requests will be reduced and your blog will be more faster.
