To create your blog posts and social media posts you need pictures. Although it is best to use your own - especially on Social Media it can be a great idea to have some places where you can find images for different topics.
You can't just Google an image and then use it - most images are copyright protected so always make sure they are free to use to avoid fines.
I frequently use Stock Photos and here I list 5 sites that offer free alternatives.
Go to the sites and download and post away! I am just happy I got to post some flowers and grapefruits that not usually fits into my blog posts.
I hope you find something you like and that fits your content.
If you did I am happy if you share! Thank you!
