Description

Description

Reason is the file has no extension name when write to path! It doesn't master under iOS, not work under React native!

Remote url Image is loaded and stored using react-native-fs and named as Z23qdxp_348:
/var/mobile/Containers/Data/Application/500161AF-8D6A-4A97-B746-0D0E12421768/Library/Caches/Z23qdxp_348

Note: If the change image name to Z23qdxp_348.jpeg the image become visible. (Works even for jpg and png image formats).

Could to be related to #23844

Steps to reproduce
  1. Download remote image
  2. Save it without extension in fileUri variable.
  3. Render <Image source={{uri: fileUri}} onError={(error) => console.error(error)}>
  4. Result: No image if name does not have extension.

Research direction

Start with the linked reproducer and the <Image source={{uri: fileUri}}> example, then compare behavior on iOS for paths with and without extensions. Done means an image saved at an extensionless local path renders successfully on iOS, without the reported missing-file error.
