+The following program displays `PNG`, `JPG` or `TIF` images
+dropped onto its window. If several files are dropped at once,
+it displays the first of them that is an image.

+```kotlin
+fun main() = application {
+    program {
+        // Create a dummy image
+        var img = drawImage(16, 16) {}
+

+
+By using `drawer.imageFit` the image is centered
+and made to fit the available window size.
