These blogs are among others that I've used to help and direct me on what I should do in terms of my own blog. As many of them are work from previous years and they have complete the course i get a great deal of insight and detail into the type of written work i should be blogging about and how the best way is on doing this.
I also use Wikipedia and official website to gain information on things i have research into. in turns of the evaluation question I've used Prezi and Slide share post to help. 
For images, I use my own or those from the internet i.g Google images
