Tell us about working with a gallery — what do you do to ensure everything works for the user?

To ensure the proper functioning of the image gallery, I usually do the following:

• Optimize image loading by using lazy loading to avoid loading all images at once and slowing down the interface.
• Ensure responsiveness — the gallery should look good and work well on different devices and screens.
• Add error handling for loading issues (for example, show a placeholder if the image fails to load).
• Implement user-friendly navigation: arrows, swipes, zooming for easy viewing.
• Cache images so that there are no delays during repeated views.
• Follow accessibility principles to make the gallery user-friendly for all users.

For example, in React, you can use the react-lazyload library for lazy loading and handle the onError event to display a backup image.
