A collection of awesome tools and resources that I think deserves to be recognised.
Stock Photography
The internet is filled with expensive stock photography services with confusing and expensive licensing terms. Instead, check out Pexels, Death to the Stock Photo, MourgeFile, two places that offer free photos for virtually unlimited/unrestricted use. Pexels, in particular, offers CC0 licensing terms, with no attribution required for personal or commercial use. Most of the photos on this site are from Pexels, as noted.
