-# <image>
+`<image>` is used to display a single image in your interface.
-### Summary
+> **Note:** `<img>` element which is usually used in HTML is not
supported in Weex, you should use `<image>` instead.
-`image` tag is used to render a specified picture, and it shouldn't
contain any child component. `<img>` is not supported currently.
+> **Note:** Weex doesn't have built-in image downloader, as relevant
download, cache, decompression mechanisms are very complicated and some open
sourced tools such as [SDWebImage](https://github.com/rs/SDWebImage) have
handled well, so please add native image adapter/handler before using `<image>`.
