I have used redbubble for my photos as I had flickr accounts, icloud accounts and several others. I saw a guy selling t-shirts recently, one of the images was mine, so I have given up on free sites...
here is a sample of my work:
taken out over the brindabella mountain range, from Mt Ainslie
Taken from Mount Ainslie, the lit area is the Executive Squadron at canberra airport
Again, same storm, but the runway is in the foreground this time.
I have tried taking photos of fireworks, so as to gain experience in delayed exposures as well. These are from the Australia Day Fireworks, 2012.
here is the URL to my portfolio.

POW! ZAP! I don't chase storms, I patiently wait for them to come to me.... Usually the soaked guy with the dry camera, atop a mountain, out of running distance from the car...
