There is nothing like a picture to brighten up a page and if you are creating a website, writing a report, or a project for school or work, you should consider using one. It has to be relevant of course, but even with a tenuous link, it can work wonders. It makes a page of dull text much more interesting. The question is, where do you find suitable images without it costing lots of money and having frustrating rules, regulation and legal issues? Pixabay is one solution.
Pixabay is a website that enables you to find and share images free of copyrights. All pictures are published under Creative Commons public domain deed CC0. This means that they can be used for any purpose without legal problems.
Many of the articles on this website use Pixabay images and it is an excellent resource. Just type a word or phrase into the search box on the home page and it displays thumbnails of related images. As the mouse passes over an image, a larger version pops up so that you can see it better.
The first row of thumbnails on the results page are always sponsored images. They are excellent, but you'll need to pay for them. Thumbnails from the second row on are all free. Click an image and the image's page opens that shows a larger version, tags, the person that posted it on the site and so on. There is a social aspect too, and you can post comments about the image, send a message to the person that posted it, or follow them so you never miss another image from them.
Click the download button and there are options to download the image in several sizes. They probably won't be exactly the size you want, but you can download the nearest one and resize it in a photo editor.
It's free and you don't have to pay anything for the images, but you can make donations if you want to (click the coffee button to send a donation so the person can buy a cup of coffee). It is entirely voluntary, so it is up to you. You can also join as a member and upload your own photos. You can accept donations (don't expect a huge income), get nice comments from people that like your photos, and even get some followers. It's a great resource.
