How to Show Image Loaders for native img tag and multiple images

Janmey Solanki


In web development, optimizing image loading is vital for providing a seamless user experience. Slow-loading images can frustrate users and impact website performance. That's where image loaders come in. Image loaders are valuable tools that streamline the loading process, ensuring images load quickly and smoothly.

In this blog post, we'll explore image loaders and how to use them for single native img tags and multiple images. Whether you're a seasoned developer or just starting, mastering image loaders will boost your website's performance. Let's dive in and learn these simple yet effective techniques!

Optimizing image loading is the key to unlocking a captivating user experience and a high-performing website.

Standard Image loading

The boredom of standard image loading 🥱

Picture this: You're browsing a website, and as the page loads, images appear one by one, pixel by pixel. The process is slow, disjointed, and hardly captivating. This is the world of standard image loading, an approach that, while functional, provides a less-than-optimal user experience. Here's why:

Slow Load Times: Standard image loading relies on the browser's default behavior, which can lead to slow load times, especially when dealing with large images. Users are left waiting, staring at a blank space or partially loaded images, which can be frustrating and detrimental to user retention.

Lack of Visual Feedback: Without any visual feedback, users may become uncertain if the page is still loading or if something is wrong. This ambiguity can create a sense of frustration and impatience, causing them to abandon the page altogether.

Poor Aesthetics: From a design standpoint, standard image loading can disrupt the visual harmony of a webpage. Images appearing haphazardly as they load can negatively impact the overall aesthetic appeal of the site.

Inconsistent Experience: Different browsers and devices may handle standard image loading differently, leading to an inconsistent experience for users. This lack of uniformity can be jarring and undermine the credibility of your website or application.

Missed Engagement Opportunities: Every aspect of your website is an opportunity to engage users. Standard image loading fails to capitalize on this by treating image loading as a mere technical process rather than an interactive and engaging element.

Basic loader for single image

When it comes to enhancing the user experience of image loading, even a simple loader can make a significant difference. In this section, we'll walk through a basic implementation of an image loader using the React framework. 😃

The Code Breakdown: Let's dissect the code step by step:

Component Definition: Our component, named BasicImageLoading, is defined using a functional approach. This is where we'll set up the structure and logic for our basic image loader.

removeAttribute Function: Here's where the magic happens. The removeAttribute function is designed to remove an attribute called "image-loading" from an HTML element. Once the image has loaded successfully, this attribute will be removed, allowing us to signify that the loading process is complete.

Image Element: The core of our loader is the img element. Here, we specify the image's source using the src attribute, provide alternative text using the alt attribute, and set the width to stretch to the container using width="100%". An id is also assigned to the image to identify it later in the removeAttribute function. Additionally, the onLoad event is crucial. This event is triggered when the image has finished loading. Upon loading completion, the onLoad event calls the removeAttribute function, which takes care of removing the "image-loading" attribute from the image element.

Placeholder: While the image is loading, we want to keep the user informed. This is where the "Loading..." text comes into play. A div element with the class name "placeholder" displays this text, creating a temporary space holder until the image loads completely.

A Sneak Peek into Enhancement:

Though this is a basic loader implementation, it already introduces an improved loading experience. Users are provided with instant visual feedback that something is happening, thanks to the "Loading..." placeholder. As the image loads, the loader smoothly transitions into the actual image, creating a seamless experience.

Stay tuned as we explore more advanced image loading techniques that further elevate user engagement and satisfaction in the upcoming sections.

Event driven loaders on multiple images

In our quest to enhance user experience, we move beyond single image loaders and dive into the world of handling multiple images with finesse. In this section, we'll explore an event-driven approach to loading multiple images, all while keeping the user engaged and informed.

The Code Unveiled:

Component Definition: The IndependentLoopLoaders component is defined using the functional approach. This component serves as a playground for our event-driven image loaders.

The images Array: Here, you've defined an array called images, containing URLs of various images you want to load. These images will showcase the capabilities of independent event-driven loading.

Image Element: For each image, you've included an img element with similar attributes to the previous example. The key difference is the src attribute, which changes dynamically based on the current image URL in the loop iteration. The onLoad event is crucial here as well. Once an image is fully loaded, the onLoad event triggers the removal of the "image-loading" attribute, just like in the single image example. This attribute removal visually signifies that the image has loaded.

Placeholder: Similar to before, a placeholder with the text "Loading..." is included under each image. What's interesting here is that you've customized the placeholder text's color for each image using inline styles. This level of customization adds a touch of uniqueness to each loader.

Styling for Image Grid: You've wrapped the images in a div that utilizes CSS Grid to create a visually pleasing arrangement of the images. The gridTemplateColumns property controls the layout, ensuring that images are evenly spaced.

A Symphony of Event-Driven Loading:

With this approach, the loading of multiple images transforms into a symphony of events. Each image and its corresponding loader operate independently, updating the UI dynamically as they load. Users are kept engaged and informed about the loading progress, all within an organized grid layout.

Stay tuned as we venture even further into the world of diverse loader styles, exploring creative ways to captivate users while optimizing image loading times.

Embracing Diversity: Exploring Different Image Loader Styles

As we continue our journey toward optimizing image loading, it's time to add a touch of creativity by incorporating various loader styles. In this section, we'll dive into the code showcasing a selection of captivating loader styles, each designed to elevate the loading experience in its own unique way.

The Code in the Spotlight: Let's uncover the intricacies of the code snippet you've shared, highlighting the diversity of image loader styles:

Component Definition: The CustomLoaders component is the canvas on which we'll paint various image loading styles. Like before, this component is defined functionally.

The images Array: Here's where the real magic happens. An array named images is created, and each entry represents an image along with its associated loader style. Each entry includes attributes like src (image URL), title (loader description), and loaderElement (the unique loader style for the specific image).

Looping Through Images: Just like in the previous section, the images array is looped through. However, instead of a generic placeholder, each image is accompanied by its distinct loader style, providing a rich and diverse loading experience.

Custom Placeholder: Instead of a generic "Loading..." placeholder, each image now has a custom placeholder. This placeholder varies in style depending on the type of loader being used for that image. This combination of images and their associated loader styles creates a visually engaging collage of loading animations.

A Kaleidoscope of Loading Styles:

With this implementation, you've unlocked a world of loading diversity. From text-based loaders to GIFs, library components, and even icon-based loaders, each image in your collection brings a distinct loading experience. This not only keeps users engaged while content loads but also adds an artistic touch to the loading process.

Stay tuned as we conclude our exploration with a summary of the different techniques covered, giving you a comprehensive toolbox to enhance image loading across your web projects.
