Speed Up Your Site: Optimize Images


background image

It is widely known that the loading time of websites has a major influence on the overall user experience. If on the age of 56K Modems people would be willing to wait even half a minute for a website to load this time span has been drastically reduced lately. The are market researches, in fact, confirming that users will just skip a site altogether if it fails to load within 4 seconds.

The first part of the “Speed Up Your Site” series will cover how to optimize images. Images can create an extra load on the size of your pages, specially if you forget to optimize them. Photoshop and similar image editing software include a feature called “Save for the web”. Always use this feature since it will reduce the image size and load time substantially.

If you do not use an image editing software or if you want something more practical you can use this online image optimizer from Dynamic Drive. It will automatically optimize gif, png and jpeg images, and it will also convert file formats if needed.

  1. Optimize Images

  3. Optimze Your CSS
  4. Use a Slash on Your Links
  5. Use the Height and Width Tags
  6. Reduce the HTTP Requests

    Great tips of Optimize Images,

    The Best method to decrease file size for a WEB image is to decrease the quality. This does NOT mean the image will not look good on a computer monitor. Digitized images are normally at a much higher quality (resolution / dots per inch) than a monitor can display. This step alone will normally reduce the file size to 1/5 of the original. Physical size will not change (Avoid resize until final step)

    I hope, it will help to all webmasters.

    Thanks for the tip about the online image optimizer. I don’t have Photoshop, although it sounds more and more like I should. In the meantime, the online image optimizer will be very helpful. Thanks again.

    For non blog sites, slicing larger graphics up in Photoshop can also help load times for sites.
