I use Wordpress.

It is very secure and customizable (dozens of layouts to choose from) while still being incredibly easy, simple and free. (Here is my Wordpress website:
http://thewayofthechicken.com).
Blogger.com is also free but I have little experience with blogger (you can see a blogger.com blog here though:

Tips:
If you wish to keep your images from being stollen, put you website name/logo on them (like I do). Most photo editing apps do this. I have used many photo editing apps for the computer... I use and highly recommend 'PhotoScape X'.
Keep it loading quickly. To keep your site loading quickly, compress images (less resolution and smaller size) when possible. The Chicken Chick uses this technique for her website. I use 'Super Smush' (it is like an application for Wordpress that is called a 'plugin'). It compresses images to makes the website load faster.
SEO. I use yoast SEO (a Wordpress plugin/app) that helps me optimize my articles and content for the search engine (it basically tells me how to make the search engine 'see' my content more easily, making it rank higher).
Visit other blogs websites. Note what features you do or do not like about them (ease of navigation, appearance and general layout). This will help you create a quality website that is easy to use and eye-catching enough to keep people intrigued.
Keep it simple. Try not to complicate things (as it takes more work and is harder to keep organized). Choose a layout and keep it from getting 'cluttered' (to many menus, to many things in the sidebar and ect...). An overfilled website is more likely to be harder to navigate and less appealing to look at.
If you have any specific questions, I'd be happy to help. However, most of my web experience is Wordpress based. Conveniently, most web-designing software has a subscription option. Subscribing means they will send you information and tips on how to build and grow your blog/website.
