On 30th June 2005 I uploaded my first photos to morguefile.com. They were fairly uninteresting shots taken with my old point-and-shoot Sony. In September 2007, I started uploading a few shots to sxc.hu.
Across these two sites, I have now had over 250,000 hi-res downloads (with a further 820K views on MorgueFile, which could be low-res downloads).
All in all, pretty amazing numbers and worth taking note of herein. And certainly testament to the popularity of these two sites.
