For developers: Retrieve image URL
You can programmatically retrieve the media URL or the thumbnail URL of an image using the image ID.
Retrieve media URL
You use the following code to retrieve the media URL of an image. The ID argument is assigned to the master version of the image.
In the code above, you first get an instance of the libraries manager. Next, you get the specified image by its master ID. If the image is found, the ResolveMediaUrl method of the image item is called and returns the media URL of the image.
