Image Caching
Image caching is a technique used to store frequently accessed images on a website’s server, so that they can be served to users more quickly when requested. This can significantly improve website performance, as images often account for a large portion of a website’s bandwidth usage.When
a user visits a website, their browser sends a request to the server for the page’s content. If the page contains images, the browser will also send requests for those images. If the images are not cached, the server will have to retrieve them from its storage system, which can take some time.
By caching the images, the server can store them in memory or on a faster storage device, so that they can be served to users more quickly.There are several techniques that can be used to implement image caching on a website.
One common technique is to use a content delivery network (CDN). A CDN is a network of servers that are located in different parts of the world. When a user requests an image from a website that is using a CDN, the CDN will serve the image from the server that is closest to the user.
This can reduce the amount of time it takes for the image to be delivered to the user.Another technique that can be used to implement image caching is to use a browser cache. A browser cache is a storage area in the user’s browser that is used to store frequently accessed files.
When a user visits a website, the browser will check its cache to see if it has a copy of the images that are being requested. If the images are in the cache, the browser will serve them from the cache instead of requesting them from the server.
This can significantly reduce the amount of time it takes for the images to be displayed to the user.Image caching is a simple but effective technique that can significantly improve website performance. By caching images, websites can reduce the amount of time it takes for images to be delivered to users, which can lead to a better user experience and increased website traffic.
Image Accessibility
Ensuring images are accessible to all users is crucial for creating an inclusive and user-friendly website.
Creating Accessible Images
- Use descriptive alt text: Provide concise, meaningful text that accurately describes the content and purpose of the image. Avoid using generic or empty alt text like “image” or “photo.”
- Ensure sufficient contrast: Images should have enough contrast between the foreground and background colors to be easily distinguishable, especially for users with low vision.
- Avoid using color alone: Don’t rely solely on color to convey information or meaning. Provide additional visual cues, such as shapes, textures, or patterns.
Benefits of Accessible Images
- Improved : Accessible images with descriptive alt text help search engines understand the content of the page, improving search rankings.
- Enhanced user experience: Accessible images allow users with disabilities to understand and interact with the content effectively.
- Compliance with legal requirements: Many countries have laws and regulations requiring websites to be accessible to users with disabilities, including providing accessible images.
Resources for Creating Accessible Images

Image Composition
Image composition is the art of arranging elements within an image to create a visually appealing and effective image. It involves the placement of objects, colors, and other elements within the frame to guide the viewer’s eye and convey a message.
Principles of Image Composition
- Rule of Thirds: Dividing the frame into thirds horizontally and vertically creates four intersection points. Placing important elements at these points can create a balanced and visually appealing composition.
- Leading Lines: Lines within an image can draw the viewer’s eye through the image and towards a focal point.
- Symmetry and Asymmetry: Symmetry can create a sense of balance and order, while asymmetry can create a more dynamic and visually interesting composition.
- Color Theory: The colors used in an image can evoke emotions and convey messages. Using complementary colors or contrasting colors can create visual interest and draw attention to specific elements.
- Negative Space: The areas of an image that are not occupied by objects can create a sense of depth and balance. Negative space can also be used to draw attention to specific elements.
Examples of Well-Composed Images
- The Mona Lisa by Leonardo da Vinci: The rule of thirds and leading lines are used to draw the viewer’s eye to Mona Lisa’s face.
- Starry Night by Vincent van Gogh: The swirling lines and contrasting colors create a sense of movement and energy.
li>The Great Wave off Kanagawa by Hokusai: The asymmetry and negative space create a sense of drama and tension.
Impact of Image Composition
Image composition has a significant impact on the overall message and effectiveness of a visual communication.
A well-composed image can capture the viewer’s attention, convey a clear message, and evoke emotions. Conversely, a poorly composed image can be confusing, distracting, and ineffective.
Common Mistakes to Avoid
- Placing the subject in the center of the frame
- Using too many elements in the frame
- Using colors that clash or are too distracting
- Not considering the negative space
- Ignoring the rule of thirds
