Blogging is a great way to practice your writing skills and to connect with your audience. It forces you to get out of your comfort zone and get out there to publish great articles.
After a while blogging can be the dream job. Of course firs you need to make sure everything is done in your checklist, but it gets easier with time.
So if you are just starting out, please don't feel discouraged. There are lots of options out there, free or paid, to get your blog online. You just need to do your own research to choose what's best for you.
Let's start with Pixabay. Here you can just go, search for a topic or browse and download your photo. However to get the high resolution image you will need to register, which is free and it takes only 2 minutes. This is one of the biggest sites I know. You can find pretty much everything you search: a giraffe, a house or a flower.
Second we have unsplash. This does not seem to be as organized as pixabay, but still the shots are great and a free photo is a free photo, so don't dismiss it just yet.
