Detailed Description

Convenience class for images with remote sources.

This class represents a fire-and-forget approach of loading images in applications. The image will load itself. Using this class also requires using QAsyncFrame or similar UI elements which allow for asynchronous image loading.

This class is used internally by the DownloadDialog class.
