Last time, we spoke about how Web components such as CSS, HTML, JavaScript, and Third Party Content affect website performance. Let’s continue to talk about a different issue, images, to understand why they create problems, and tips to identify these problems.

 

Images definitely enhance the look and feel of a website. They significantly contribute to the overall user experience. If images don’t load when you visit a website for the very first time, chances are it’s going to affect your perception about that site and its content. You might never return to that site. Your users are going to be thinking the same thing when they visit your website. Sometimes images that tell an important story about your product or service won’t load, leaving the page with just text. Let’s look at why this issue occurs.

 

The image loads but it looks incorrect. Sometimes when images load on a website, they don’t look the way they do in other browsers. This could happen if you’re using Web accelerator software, which reduces image quality.

Plug-in issues. Some plug-ins installed in the browser allows images to load only on the very first viewing. They may not load during successive visits to the same page, even after refreshing.

Cache and cookies. A corrupt cache file or cookies can sometimes prevent images from loading.

Image permissions. Some browsers prevent certain websites from loading images just to increase load speed.

Internet Security. Antivirus, firewall, and other security programs may block images and prevent them from loading.

Pathnames to image files. Images that contain backslashes in their URL might have issues displaying in the browser. This may vary from browser to browser.

 

4 Tips for Monitoring Image Issues

1. Record your Web transaction. Recording a transaction will establish how well your applications are performing. You can then compare this to your baseline and identify what page element is causing the issue.

2. Use image matching. You can define the number of seconds it takes for an image to load using image matching. Monitoring this will tell you if the image has loaded within the specified time. Then you know if the transaction passed or failed.

3. Monitor page load times. Establish a baseline for how much time it should ideally take applications to load. Then monitor the load times of each step in the page. If a step loads slowly or fails to load, you should receive an alert about the problem.

4. Enable JavaScript settings. Ensure JavaScript is enabled in your browser. Monitoring JavaScript will make sure the browser displays images and other features in your application.
