Obtaining the image URL from the camera roll involves accessing the stored image’s unique identifier or file path within the device’s file system. Different platforms and programming languages may have specific methods or APIs to retrieve this URL. For instance, in iOS, you can use the UIImagePickerController library to access the camera roll and obtain the selected image’s URL.
Accessing the camera roll allows you to retrieve and utilize images stored on the device. This can be beneficial for various purposes, such as displaying images in an app, processing them, or sharing them with others. Additionally, having the image URL enables you to access the image’s metadata, such as its resolution, size, and other relevant information.
