Well I did it, I got all my images ready and changed them to the right size. I even read the terms and conditions. A good thing to do when you are entering a competition. I am so proud of myself.
If you are interested in entering competitions then there is a website that is apparently very good for finding them, and they help narrow down the right ones for you. The site is called Photo Contest Insider.
The image with this post is one of the ones I entered.
