Where to search and download some free and nice images to be used on my websites?
The best one for searching the free images is still Google. Google Image Search has a “Advanced Image Search” where you can choose the usage rights. Choose the “free to use, share, or modify, even commercially” option will lead you to the most free images. I have prepared a link for you with the usage right selected:
Another 2 good images providers:
Pixabay – lots of good free high quality images.
Freepic – lots good vector images, suitable for slides or posters.
Note: double check each image’s license before you use it.
