Question 1

Should I use image-promise or native img.decode for loading images?

Accepted Answer

Native img.decode() is now the recommended approach in modern browsers as it avoids extra dependencies and is built-in. image-promise offers a simpler promise API for multiple images and custom attributes, but it's deprecated and less future-proof.

Question 2

How to set CORS attributes when loading images with image-promise?

Accepted Answer

Pass a second argument with attributes, e.g., loadImage(url, { crossorigin: 'anonymous' }). This sets the crossorigin attribute before loading, enabling CORS for uses like canvas.toDataURL().

Question 3

What are the best alternatives to image-promise now?

Accepted Answer

For simple cases, use native img.decode() or the Image() constructor with promises. For more features, consider libraries like imagesloaded, or framework-specific solutions in React or Vue for image handling.

Question 4

Is image-promise still maintained or supported?

Accepted Answer

No, the README explicitly states it's deprecated and recommends using native img.decode() instead, so there will be no further development or community support.

Question 5

Can image-promise handle lazy loading of images?

Accepted Answer

No, it only handles basic image loading; for lazy loading, you need additional logic or dedicated libraries like lozad.js, or use the native loading='lazy' attribute on <img> elements.

Question 6

How does image-promise compare to using fetch for image loading?

Accepted Answer

image-promise focuses on <img> elements and URLs with a simple API, while fetch can handle raw image data but requires more code for rendering. fetch is more flexible but image-promise was designed for direct image element integration.
