Is it possible to flash a factory image from the openwrt web interface?

Question

network hardware

Worth openwrt 14.07. I installed the router's native firmware from the web interface using firmware 14.07-squashfs-factory. Is it possible to download the same factory firmware again and flash it from the openwrt web interface.
It's just that the web interface says this:
Download a sysupgrade-compatible image to replace the current firmware. Check the "Save settings" box to save the current configuration (requires an OpenWrt compatible firmware image).
And I want to flash not a sysupgrade image, but a factory image.

Answer 1

depending on which router

Answer 2
