CW, SSB and the common digital modes aren't the only use for QRP. Slow Scan TV can work as well. You can download software (like MMSSTV) or use a mobile app to send audio to your SSB transceiver. If you're not doing a test with someone on the other end you could monitor your signal with a live SSTV cam. 

Your QRP signal will be a bit grainer than those running high power. Tips to minimise the effects of this including using high contrast slides and using a good solid font for your callsign. Repeating your callsign can help defend against interference bursts.  It also helps to use a slower transmitting speed. 

Below is an example SSTV webcam. I was running 5w on 80m from about 300 km away. 

Below is an account of a milliwatt test with VK4VJR

This one's only a couple of days ago. It's an SSTV contact over 450km in the middle of the day on 3.5 MHz.

Give SSTV a go. Even with QRP. Let me know the results you get in the comments below.

PS: Into low power amateur radio? Minimum QRP is the top-selling manual on the equipment, antennas, operating and strategy of successful QRP operating. It's available for under $US 5 each in electronic form. Or you can get a paperback version. Visit VK3YE Radio Books to find out more.
