HU6900 series resolution for still photos?

[rejected]

I'd like to watch digital SLR shots (*.jpg in 24 MPix resolution) on HU6900 series.
What is HGU6900 series resolution for *.jpg files read from USB stick attached directly to USB input, camera connected to USB input or from DLNA NAS server through home LAN?
Is there any difference which TV USB input to chose (there are two USB 2.0 an one USB 3.0 sockets in HU6900 series) besides speed?
Is that possible to zoom the pictures in any way (i.e. to 100% pixel by pixel) when watching?
