Does `display:none` Prevent Image Loading in Modern Browsers?

Unveiling the Impact of "display:none" on Image Loading

Responsive web design advocates often rely on the "display:none" CSS property to enhance mobile browsing experiences. However, a crucial question arises: does this property prevent images from loading, or does it still fetch them in the background?

Truth Unveiled: The Evolving Browsers

Initially, setting an image's "display" to "none" would hide it without affecting its loading. However, modern browsers have become more intelligent. They can now detect when an image is unnecessary for the visible portion of the page and skip its loading.

Chrome, specifically, has the ability to prevent image loading if the parent element of the image is hidden. This behavior can be observed here: http://jsfiddle.net/tnk3j08s/.

Alternative Approaches to Prevent Loading

If you aim to prevent an image's loading completely, consider these alternatives:

• Removing the IMG Element: Simply exclude the IMG element from the document.
• Modifying the IMG Source: Update the IMG's src attribute to "data:" or "about:blank" to prevent actual image fetching.

Important Notes

For the above strategies to work effectively, your image should not be visible on the initial screen and shouldn't be lazily loaded. If these conditions are not met, the image may still be loaded but hidden.
