I thought I'd share something that I keep in my toolbox for various projects that I bootstrap, from time to time. Here is my list of sites that offer images and icons, either in the public domain, or with licensing that allow commercial use. These resources are specifically ones that are of great quality, in my opinion. No clipart here. Note: My article image is from Unsplash https://unsplash.com/photos/CmF_5GYc6c0. :-)
Enjoy!
