Property Value

The value which is true when low-resolution image should be used; false otherwise.


When preview image is generated, its width and height is divided by the value stored in the PreviewImageResizeRatio property. This image is downloaded to the browser entirely and stretched at the container. After that high resolution portion of the image is downloaded to client and displayed in the viewport. This way user can preview (with very poor quality though) the portion of the image, and he can scroll to the necessary position on the image before high resolution fragment is loaded.

Default value is true.
