App to send photos from Windows network share to Chromecast

[viragored]

Hi - does anyone know of an app that will actually work to find photos in shares on my Windows network, and send them to Google Chromecast?
So far - Google Photos works, but only for photos that are on the Android device
- Apps such as File Commander offer to find and send pictures to Google Photos, but as soon as the option is selected Photos disconnects from Chromecast
- VLC works well for casting videos on the network, but it won't find jpg or RAW files

Target Android devices are all Samsung, and include S7, A5 and Tab A

All help will be most welcome!
