I have on my site a number of wonderful photographs and icons. Many of them are released under Creative Commons licensing to use for free with acknowledgement. I am happy to provide that here:
Many of my photos are purchased through DTTSP (Death to the Stock Photo) and while I did pay for them I wish to support their efforts to provide excellent stock photos in a way that the average person can afford.
Other photos are from Unsplash, one of my favourite online places for photos.
