When building modern websites one of the biggest issues is finding decent pictures to embed. Most people are horrible at photography, and the price of stock photos from most services while reasonable are generally more than most people want to pay. You want to add a picture as your featured image thumbnail, but you don’t want to pay $5 for it (Especially when you’re publishing 5+ posts a day.)
Pexels.com is a great option. They have very a selection of high quality photographs that are 100% free to use for either business or commercial purposes:
It’s hard to understand complex licenses that is why all photos on Pexels are licensed under the Creative Commons Zero (CC0) license. This means you can copy, modify, distribute and perform the photos. The pictures are free for personal and even for commercial use. All without asking for permission or setting a link to the source. So that attribution is not required. All in all the photos are completely free to be used for any legal purpose.
The CC0 license was released by the non-profit organization Creative Commons (CC). Get more information about the license on the official license page.
Identifiable people may not appear in a bad light or in a way that they may find offensive, unless they give their consent.
They say that they currently have 2300 images and are adding approx. 70 per week. This may not be good enough for a major publication but as far as GeekBrainDump.com is concerned it’s just fine.

There are other royalty free sites with high quality images, but the licensing can be problematic. They may only allow for a certain number of impressions of the image, or only allow them to be used in specific types of material. Always read the licensing!
