# ImageProvider
{{ doctable("Quick", "QCoroImageProvider") }}
Coroutines based implementation of [`QQuickImaqeProvider`][qdoc-imageprovider].
To use `QCoro::ImageProvider`, you need to create a subclass of it, and implement the `asyncRequestImage` function, as shown in the example below:
```cpp
#include <QCoro/QCoroImageProvider>
class IconImageProvider : public QCoro::ImageProvider
{
public:
QCoro::Task<QImage> asyncRequestImage(const QString &id, const QSize &) override;
};
```
The subclass [can be registered with a `QQmlEngine`][qdoc-addimageprovider] like any `QQuickImageProvider` subclass.
